Changelog

AutoRAG now includes a Metrics tab that shows how your data is indexed and searched. Get a clear view of the health of your indexing pipeline, compare usage between ai-search and search, and see which files are retrieved most often.

You can find these metrics within each AutoRAG instance:

• Indexing: Track how files are ingested and see status changes over time.
• Search breakdown: Compare usage between ai-search and search endpoints.
• Top file retrievals: Identify which files are most frequently retrieved in a given period.

Try it today in AutoRAG.

Rate Limiting within Cloudflare Workers is now Generally Available (GA).

The ratelimit binding is now stable and recommended for all production workloads. Existing deployments using the unsafe binding will continue to function to allow for a smooth transition.

For more details, refer to Workers Rate Limiting documentation.

In workers-rs ↗, Rust panics were previously non-recoverable. A panic would put the Worker into an invalid state, and further function calls could result in memory overflows or exceptions.

Now, when a panic occurs, in-flight requests will throw 500 errors, but the Worker will automatically and instantly recover for future requests.

This ensures more reliable deployments. Automatic panic recovery is enabled for all new workers-rs deployments as of version 0.6.5, with no configuration required.

Rust Workers are built with Wasm Bindgen, which treats panics as non-recoverable. After a panic, the entire Wasm application is considered to be in an invalid state.

We now attach a default panic handler in Rust:

std::panic::set_hook(Box::new(move |panic_info| {
  hook_impl(panic_info);
}));

Which is registered by default in the JS initialization:

import { setPanicHook } from "./index.js";
setPanicHook(function (err) {
	console.error("Panic handler!", err);
});

When a panic occurs, we reset the Wasm state to revert the Wasm application to how it was when the application started.

We worked upstream on the Wasm Bindgen project to implement a new --experimental-reset-state-function compilation option ↗ which outputs a new __wbg_reset_state function.

This function clears all internal state related to the Wasm VM, and updates all function bindings in place to reference the new WebAssembly instance.

One other necessary change here was associating Wasm-created JS objects with an instance identity. If a JS object created by an earlier instance is then passed into a new instance later on, a new "stale object" error is specially thrown when using this feature.

Building on this new Wasm Bindgen feature, layered with our new default panic handler, we also added a proxy wrapper to ensure all top-level exported class instantiations (such as for Rust Durable Objects) are tracked and fully reinitialized when resetting the Wasm instance. This was necessary because the workerd runtime will instantiate exported classes, which would then be associated with the Wasm instance.

This approach now provides full panic recovery for Rust Workers on subsequent requests.

Of course, we never want panics, but when they do happen they are isolated and can be investigated further from the error logs - avoiding broader service disruption.

In the future, full support for recoverable panics could be implemented without needing reinitialization at all, utilizing the WebAssembly Exception Handling ↗ proposal, part of the newly announced WebAssembly 3.0 ↗ specification. This would allow unwinding panics as normal JS errors, and concurrent requests would no longer fail.

We're making significant improvements to the reliability of Rust Workers ↗. Join us in #rust-on-workers on the Cloudflare Developers Discord ↗ to stay updated.

You can now route private traffic to Cloudflare Tunnel based on a hostname or domain, moving beyond the limitations of IP-based routing. This new capability is free for all Cloudflare One customers.

Previously, Tunnel routes could only be defined by IP address or CIDR range. This created a challenge for modern applications with dynamic or ephemeral IP addresses, often forcing administrators to maintain complex and brittle IP lists.

What’s new:

• Hostname & Domain Routing: Create routes for individual hostnames (e.g., payroll.acme.local) or entire domains (e.g., *.acme.local) and direct their traffic to a specific Tunnel.
• Simplified Zero Trust Policies: Build resilient policies in Cloudflare Access and Gateway using stable hostnames, making it dramatically easier to apply per-resource authorization for your private applications.
• Precise Egress Control: Route traffic for public hostnames (e.g., bank.example.com) through a specific Tunnel to enforce a dedicated source IP, solving the IP allowlist problem for third-party services.
• No More IP Lists: This feature makes the workaround of maintaining dynamic IP Lists for Tunnel connections obsolete.

Get started in the Tunnels section of the Zero Trust dashboard with your first private hostname or public hostname route.

Learn more in our blog post ↗.

We recently increased the available disk space from 8 GB to 20 GB for all plans. Building on that improvement, we’re now doubling the CPU power available for paid plans — from 2 vCPU to 4 vCPU.

These changes continue our focus on making Workers Builds faster and more reliable.

• Fast build times: Even single-threaded workloads benefit from having more vCPUs
• 2x faster multi-threaded builds: Tools like esbuild ↗ and webpack ↗ can now utilize additional cores, delivering near-linear performance scaling

All other build limits — including memory, build minutes, and timeout remain unchanged.

To prevent the accidental exposure of applications, we've updated how Worker preview URLs (<PREVIEW>-<WORKER_NAME>.<SUBDOMAIN>.workers.dev) are handled. We made this change to ensure preview URLs are only active when intentionally configured, improving the default security posture of your Workers.

We performed a one-time update to disable preview URLs for existing Workers where the workers.dev subdomain was also disabled.

Because preview URLs were historically enabled by default, users who had intentionally disabled their workers.dev route may not have realized their Worker was still accessible at a separate preview URL. This update was performed to ensure that using a preview URL is always an intentional, opt-in choice.

If your Worker was affected, its preview URL (<PREVIEW>-<WORKER_NAME>.<SUBDOMAIN>.workers.dev) will now direct to an informational page explaining this change.

How to Re-enable Your Preview URL

If your preview URL was disabled, you can re-enable it via the Cloudflare dashboard by navigating to your Worker's Settings page and toggling on the Preview URL.

Alternatively, you can use Wrangler by adding the preview_urls = true setting to your Wrangler file and redeploying the Worker.

{
  "preview_urls": true
}

preview_urls = true

Note: You can set preview_urls = true with any Wrangler version that supports the preview URL flag (v3.91.0+). However, we recommend updating to v4.34.0 or newer, as this version defaults preview_urls to false, ensuring preview URLs are always enabled by explicit choice.

Zero Trust Dashboard has a brand new, AI-powered search functionality. You can search your account by resources (applications, policies, device profiles, settings, etc.), pages, products, and more.

Ask Cloudy — You can also ask Cloudy, our AI agent, questions about Cloudflare Zero Trust. Cloudy is trained on our developer documentation and implementation guides, so it can tell you how to configure functionality, best practices, and can make recommendations.

Cloudy can then stay open with you as you move between pages to build configuration or answer more questions.

Find Recents — Recent searches and Cloudy questions also have a new tab under Zero Trust Overview.

Three months ago we announced the public beta of remote bindings for local development. Now, we're excited to say that it's available for everyone in Wrangler, Vite, and Vitest without using an experimental flag!

With remote bindings, you can now connect to deployed resources like R2 buckets and D1 databases while running Worker code on your local machine. This means you can test your local code changes against real data and services, without the overhead of deploying for each iteration.

To enable remote bindings, add "remote" : true to each binding that you want to rely on a remote resource running on Cloudflare:

{
	"name": "my-worker",
	// Set this to today's date
	"compatibility_date": "2026-08-21",

	"r2_buckets": [
		{
			"bucket_name": "screenshots-bucket",
			"binding": "screenshots_bucket",
			"remote": true,
		},
	],
}

name = "my-worker"
# Set this to today's date
compatibility_date = "2026-08-21"

[[r2_buckets]]
bucket_name = "screenshots-bucket"
binding = "screenshots_bucket"
remote = true

When remote bindings are configured, your Worker still executes locally, but all binding calls are proxied to the deployed resource that runs on Cloudflare's network.

You can try out remote bindings for local development today with:

• Wrangler v4.37.0
• The Cloudflare Vite Plugin
• The Cloudflare Vitest Plugin

This week's update

This week's focus highlights newly disclosed vulnerabilities in DevOps tooling, data visualization platforms, and enterprise CMS solutions. These issues include sensitive information disclosure and remote code execution, putting organizations at risk of credential leakage, unauthorized access, and full system compromise.

Key Findings

• Argo CD (CVE-2025-55190): Exposure of sensitive information could allow attackers to access credential data stored in configurations, potentially leading to compromise of Kubernetes workloads and secrets.

• DataEase (CVE-2025-57773): Insufficient input validation enables JNDI injection and insecure deserialization, resulting in remote code execution (RCE). Successful exploitation grants attackers control over the application server.

• Sitecore (CVE-2025-53694): A sensitive information disclosure flaw allows unauthorized access to confidential information stored in Sitecore deployments, raising the risk of data breaches and privilege escalation.

Impact

These vulnerabilities expose organizations to serious risks, including credential theft, unauthorized access, and full system compromise. Argo CD's flaw may expose Kubernetes secrets, DataEase exploitation could give attackers remote execution capabilities, and Sitecore's disclosure issue increases the likelihood of sensitive data leakage and business impact.

Administrators are strongly advised to apply vendor patches immediately, rotate exposed credentials, and review access controls to mitigate these risks.

We’re excited to announce that Email security customers can now choose their preferred mail processing location directly from the UI when onboarding a domain. This feature is available for the following onboarding methods: MX, BCC, and Journaling.

Customers can now select where their email is processed. The following regions are supported:

• Germany
• India
• Australia

Global processing remains the default option, providing flexibility to meet both compliance requirements or operational preferences.

When onboarding a domain with MX, BCC, or Journaling:

1. Select the desired processing location (Germany, India, or Australia).
2. The UI will display updated processing addresses specific to that region.
3. For MX onboarding, if your domain is managed by Cloudflare, you can automatically update MX records directly from the UI.

This feature is available across these Email security packages:

• Advantage
• Enterprise
• Enterprise + PhishGuard

We’re expanding the list of processing locations to match our Data Localization Suite (DLS) footprint, giving customers the broadest set of regional options in the market without the complexity of self-hosting.

D1 now detects read-only queries and automatically attempts up to two retries to execute those queries in the event of failures with retryable errors. You can access the number of execution attempts in the returned response metadata property total_attempts.

At the moment, only read-only queries are retried, that is, queries containing only the following SQLite keywords: SELECT, EXPLAIN, WITH. Queries containing any SQLite keyword ↗ that leads to database writes are not retried.

The retry success ratio among read-only retryable errors varies from 5% all the way up to 95%, depending on the underlying error and its duration (like network errors or other internal errors).

The retry success ratio among all retryable errors is lower, indicating that there are write-queries that could be retried. Therefore, we recommend D1 users to continue applying retries in their own code for queries that are not read-only but are idempotent according to the business logic of the application.

D1 ensures that any retry attempt does not cause database writes, making the automatic retries safe from side-effects, even if a query causing changes slips through the read-only detection. D1 achieves this by checking for modifications after every query execution, and if any write occurred due to a retry attempt, the query is rolled back.

The read-only query detection heuristics are simple for now, and there is room for improvement to capture more cases of queries that can be retried, so this is just the beginning.

Magic WAN and WARP Connector users can now securely route their DNS traffic to the Gateway resolver without exposing traffic to the public Internet.

Routing DNS traffic to the Gateway resolver allows DNS resolution and filtering for traffic coming from private networks while preserving source internal IP visibility. This ensures Magic WAN users have full integration with our Cloudflare One features, including Internal DNS and hostname-based policies.

To configure DNS filtering, change your Magic WAN or WARP Connector DNS settings to use Cloudflare's shared resolver IPs, 172.64.36.1 and 172.64.36.2. Once you configure DNS resolution and filtering, you can use Source Internal IP as a traffic selector in your resolver policies for routing private DNS traffic to your Internal DNS.

Directly from Log Search results, customers can pivot to other parts of the Cloudflare dashboard to immediately take action as a result of their investigation.

From the http_requests or fw_events dataset results, right click on an IP Address or JA3 Fingerprint to pivot to the Investigate portal to lookup the reputation of an IP address or JA3 fingerprint.

Easily learn about error codes by linking directly to our documentation from the EdgeResponseStatus or OriginResponseStatus fields.

From the gateway_http dataset, click on a policyid to link directly to the Zero Trust dashboard to review or make changes to a specific Gateway policy.

The results table view of Log Search has been updated with additional functionality and a more streamlined user experience. Users can now easily:

• Remove/add columns.
• Resize columns.
• Sort columns.
• Copy values from any field.

The number of recent versions available for a Worker rollback has been increased from 10 to 100.

This allows you to:

• Promote any of the 100 most recent versions to be the active deployment.

• Split traffic using gradual deployments between your latest code and any of the 100 most recent versions.

You can do this through the Cloudflare dashboard or with Wrangler's rollback command

Learn more about versioned deployments and rollbacks.

A new Beta release for the Windows WARP client is now available on the beta releases downloads page.

This release contains minor fixes and improvements including enhancements to Proxy mode for even faster resolution. The MASQUE protocol is now the only protocol that can use Proxy mode. If you previously configured a device profile to use Proxy mode with Wireguard, you will need to select a new WARP mode or all devices matching the profile will lose connectivity.

Changes and improvements

• Enhancements to Proxy mode for even faster resolution. The MASQUE protocol is now the only protocol that can use Proxy mode. If you previously configured a device profile to use Proxy mode with Wireguard, you will need to select a new WARP mode or all devices matching the profile will lose connectivity.
• Improvement to keep TCP connections up the first time WARP connects on devices so that remote desktop sessions (such as RDP or SSH) continue to work.
• Improvements to maintain Global WARP Override settings when switching between organization configurations.
• The MASQUE protocol is now the default protocol for all new WARP device profiles.
• Improvement to limit idle connections in DoH mode to avoid unnecessary resource usage that can lead to DoH requests not resolving.

Known issues

• For Windows 11 24H2 users, Microsoft has confirmed a regression that may lead to performance issues like mouse lag, audio cracking, or other slowdowns. Cloudflare recommends users experiencing these issues upgrade to a minimum Windows 11 24H2 KB5062553 or higher for resolution.

• Devices using WARP client 2025.4.929.0 and up may experience Local Domain Fallback failures if a fallback server has not been configured. To configure a fallback server, refer to Route traffic to fallback server.

• Devices with KB5055523 installed may receive a warning about Win32/ClickFix.ABA being present in the installer. To resolve this false positive, update Microsoft Security Intelligence to version 1.429.19.0 or later.

• DNS resolution may be broken when the following conditions are all true:

  • WARP is in Secure Web Gateway without DNS filtering (tunnel-only) mode.
  • A custom DNS server address is configured on the primary network adapter.
  • The custom DNS server address on the primary network adapter is changed while WARP is connected.

  To work around this issue, reconnect the WARP client by toggling off and back on.

A new Beta release for the macOS WARP client is now available on the beta releases downloads page.

This release contains minor fixes and improvements including enhancements to Proxy mode for even faster resolution. The MASQUE protocol is now the only protocol that can use Proxy mode. If you previously configured a device profile to use Proxy mode with Wireguard, you will need to select a new WARP mode or all devices matching the profile will lose connectivity.

Changes and improvements

• Enhancements to Proxy mode for even faster resolution. The MASQUE protocol is now the only protocol that can use Proxy mode. If you previously configured a device profile to use Proxy mode with Wireguard, you will need to select a new WARP mode or all devices matching the profile will lose connectivity.
• Fixed a bug preventing the warp-diag captive-portal command from running successfully due to the client not parsing SSID on macOS.
• Improvements to maintain Global WARP Override settings when switching between organization configurations.
• The MASQUE protocol is now the default protocol for all new WARP device profiles.
• Improvement to limit idle connections in DoH mode to avoid unnecessary resource usage that can lead to DoH requests not resolving.

Known issues

• macOS Sequoia: Due to changes Apple introduced in macOS 15.0.x, the WARP client may not behave as expected. Cloudflare recommends the use of macOS 15.4 or later.
• Devices using WARP client 2025.4.929.0 and up may experience Local Domain Fallback failures if a fallback server has not been configured. To configure a fallback server, refer to Route traffic to fallback server.

We've shipped a new release for the Agents SDK ↗ bringing full compatibility with AI SDK v5 ↗ and introducing automatic message migration that handles all legacy formats transparently.

This release includes improved streaming and tool support, tool confirmation detection (for "human in the loop" systems), enhanced React hooks with automatic tool resolution, improved error handling for streaming responses, and seamless migration utilities that work behind the scenes.

This makes it ideal for building production AI chat interfaces with Cloudflare Workers AI models, agent workflows, human-in-the-loop systems, or any application requiring reliable message handling across SDK versions — all while maintaining backward compatibility.

Additionally, we've updated workers-ai-provider v2.0.0, the official provider for Cloudflare Workers AI models, to be compatible with AI SDK v5.

Creates a new chat interface with enhanced v5 capabilities.

// Basic chat setup
const { messages, sendMessage, addToolResult } = useAgentChat({
	agent,
	experimental_automaticToolResolution: true,
	tools,
});

// With custom tool confirmation
const chat = useAgentChat({
	agent,
	experimental_automaticToolResolution: true,
	toolsRequiringConfirmation: ["dangerousOperation"],
});

Tools are automatically categorized based on their configuration:

const tools = {
	// Auto-executes (has execute function)
	getLocalTime: {
		description: "Get current local time",
		inputSchema: z.object({}),
		execute: async () => new Date().toLocaleString(),
	},

	// Requires confirmation (no execute function)
	deleteFile: {
		description: "Delete a file from the system",
		inputSchema: z.object({
			filename: z.string(),
		}),
	},

	// Server-executed (no client confirmation)
	analyzeData: {
		description: "Analyze dataset on server",
		inputSchema: z.object({ data: z.array(z.number()) }),
		serverExecuted: true,
	},
} satisfies Record<string, AITool>;

Send messages using the new v5 format with parts array:

// Text message
sendMessage({
	role: "user",
	parts: [{ type: "text", text: "Hello, assistant!" }],
});

// Multi-part message with file
sendMessage({
	role: "user",
	parts: [
		{ type: "text", text: "Analyze this image:" },
		{ type: "image", image: imageData },
	],
});

Simplified logic for detecting pending tool confirmations:

const pendingToolCallConfirmation = messages.some((m) =>
	m.parts?.some(
		(part) => isToolUIPart(part) && part.state === "input-available",
	),
);

// Handle tool confirmation
if (pendingToolCallConfirmation) {
	await addToolResult({
		toolCallId: part.toolCallId,
		tool: getToolName(part),
		output: "User approved the action",
	});
}

Seamlessly handle legacy message formats without code changes.

// All these formats are automatically converted:

// Legacy v4 string content
const legacyMessage = {
	role: "user",
	content: "Hello world",
};

// Legacy v4 with tool calls
const legacyWithTools = {
	role: "assistant",
	content: "",
	toolInvocations: [
		{
			toolCallId: "123",
			toolName: "weather",
			args: { city: "SF" },
			state: "result",
			result: "Sunny, 72°F",
		},
	],
};

// Automatically becomes v5 format:
// {
//   role: "assistant",
//   parts: [{
//     type: "tool-call",
//     toolCallId: "123",
//     toolName: "weather",
//     args: { city: "SF" },
//     state: "result",
//     result: "Sunny, 72°F"
//   }]
// }

Migrate tool definitions to use the new inputSchema property.

// Before (AI SDK v4)
const tools = {
	weather: {
		description: "Get weather information",
		parameters: z.object({
			city: z.string(),
		}),
		execute: async (args) => {
			return await getWeather(args.city);
		},
	},
};

// After (AI SDK v5)
const tools = {
	weather: {
		description: "Get weather information",
		inputSchema: z.object({
			city: z.string(),
		}),
		execute: async (args) => {
			return await getWeather(args.city);
		},
	},
};

Seamless integration with Cloudflare Workers AI models through the updated workers-ai-provider v2.0.0.

Use Cloudflare Workers AI models directly in your agent workflows:

import { createWorkersAI } from "workers-ai-provider";
import { useAgentChat } from "agents/ai-react";

// Create Workers AI model (v2.0.0 - same API, enhanced v5 internals)
const model = createWorkersAI({
	binding: env.AI,
})("@cf/meta/llama-3.2-3b-instruct");

Workers AI models now support v5 file handling with automatic conversion:

// Send images and files to Workers AI models
sendMessage({
	role: "user",
	parts: [
		{ type: "text", text: "Analyze this image:" },
		{
			type: "file",
			data: imageBuffer,
			mediaType: "image/jpeg",
		},
	],
});

// Workers AI provider automatically converts to proper format

Enhanced streaming support with automatic warning detection:

// Streaming with Workers AI models
const result = await streamText({
	model: createWorkersAI({ binding: env.AI })("@cf/meta/llama-3.2-3b-instruct"),
	messages,
	onChunk: (chunk) => {
		// Enhanced streaming with warning handling
		console.log(chunk);
	},
});

Update your imports to use the new v5 types:

// Before (AI SDK v4)
import type { Message } from "ai";
import { useChat } from "ai/react";

// After (AI SDK v5)
import type { UIMessage } from "ai";
// or alias for compatibility
import type { UIMessage as Message } from "ai";
import { useChat } from "@ai-sdk/react";

Deploying static site to Workers is now easier. When you run wrangler deploy [directory] or wrangler deploy --assets [directory] without an existing configuration file, Wrangler CLI now guides you through the deployment process with interactive prompts.

Before: Required remembering multiple flags and parameters

wrangler deploy --assets ./dist --compatibility-date 2025-09-09 --name my-project

After: Simple directory deployment with guided setup

wrangler deploy dist
# Interactive prompts handle the rest as shown in the example flow below

Interactive prompts for missing configuration:

• Wrangler detects when you're trying to deploy a directory of static assets
• Prompts you to confirm the deployment type
• Asks for a project name (with smart defaults)
• Automatically sets the compatibility date to today

Automatic configuration generation:

• Creates a wrangler.jsonc file with your deployment settings
• Stores your choices for future deployments
• Eliminates the need to remember complex command-line flags

# Deploy your built static site
wrangler deploy dist

# Wrangler will prompt:
✔ It looks like you are trying to deploy a directory of static assets only. Is this correct? … yes
✔ What do you want to name your project? … my-astro-site

# Automatically generates a wrangler.jsonc file and adds it to your project:
{
  "name": "my-astro-site",
  "compatibility_date": "2025-09-09",
  "assets": {
    "directory": "dist"
  }
}

# Next time you run wrangler deploy, this will use the configuration in your newly generated wrangler.jsonc file
wrangler deploy

• You must use Wrangler version 4.24.4 or later in order to use this feature

Now, Magic WAN customers can configure a custom IKE ID for their IPsec tunnels. Customers that are using Magic WAN and a VeloCloud SD-WAN device together can utilize this new feature to create a high availability configuration.

This feature is available via API only. Customers can read the Magic WAN documentation to learn more about the Custom IKE ID feature and the API call to configure it.

Two-factor authentication is the best way to help protect your account from account takeovers, but if you lose your second factor, you could be locked out of your account. Lock outs are one of the top reasons customers contact Cloudflare support, and our policies often don't allow us to bypass two-factor authentication for customers that are locked out. Today we are releasing an improvement where Cloudflare will periodically remind you to securely save your backup codes so you don't get locked out in the future.

• Two-factor authentication

This week's update

This week’s focus highlights newly disclosed vulnerabilities in web frameworks, enterprise applications, and widely deployed CMS plugins. The vulnerabilities include SSRF, authentication bypass, arbitrary file upload, and remote code execution (RCE), exposing organizations to high-impact risks such as unauthorized access, system compromise, and potential data exposure. In addition, security rule enhancements have been deployed to cover general command injection and server-side injection attacks, further strengthening protections.

Key Findings

• Next.js (CVE-2025-57822): Improper handling of redirects in custom middleware can lead to server-side request forgery (SSRF) when user-supplied headers are forwarded. Attackers could exploit this to access internal services or cloud metadata endpoints. The issue has been resolved in versions 14.2.32 and 15.4.7. Developers using custom middleware should upgrade and verify proper redirect handling in next() calls.

• ScriptCase (CVE-2025-47227, CVE-2025-47228): In the Production Environment extension in Netmake ScriptCase through 9.12.006 (23), two vulnerabilities allow attackers to reset admin accounts and execute system commands, potentially leading to full compromise of affected deployments.

• Sar2HTML (CVE-2025-34030): In Sar2HTML version 3.2.2 and earlier, insufficient input sanitization of the plot parameter allows remote, unauthenticated attackers to execute arbitrary system commands. Exploitation could compromise the underlying server and its data.

• Zhiyuan OA (CVE-2025-34040): An arbitrary file upload vulnerability exists in the Zhiyuan OA platform. Improper validation in the wpsAssistServlet interface allows unauthenticated attackers to upload crafted files via path traversal, which can be executed on the web server, leading to remote code execution.

• WordPress:Plugin:InfiniteWP Client (CVE-2020-8772): A vulnerability in the InfiniteWP Client plugin allows attackers to perform restricted actions and gain administrative control of connected WordPress sites.

Impact

These vulnerabilities could allow attackers to gain unauthorized access, execute malicious code, or take full control of affected systems. The Next.js SSRF flaw may expose internal services or cloud metadata endpoints to attackers. Exploitations of ScriptCase and Sar2HTML could result in remote code execution, administrative takeover, and full server compromise. In Zhiyuan OA, the arbitrary file upload vulnerability allows attackers to execute malicious code on the web server, potentially exposing sensitive data and applications. The authentication bypass in WordPress InfiniteWP Client enables attackers to gain administrative access, risking data exposure and unauthorized control of connected sites.

Administrators are strongly advised to apply vendor patches immediately, remove unsupported software, and review authentication and access controls to mitigate these risks.

All bidirectional tunnel health check return packets are accepted by any Magic on-ramp.

Previously, when a Magic tunnel had a bidirectional health check configured, the bidirectional health check would pass when the return packets came back to Cloudflare over the same tunnel that was traversed by the forward packets.

There are SD-WAN devices, like VeloCloud, that do not offer controls to steer traffic over one tunnel versus another in a high availability tunnel configuration.

Now, when a Magic tunnel has a bidirectional health check configured, the bidirectional health check will pass when the return packet traverses over any tunnel in a high availability configuration.
