Changelog

This week's update spotlights several critical vulnerabilities across Citrix NetScaler Memory Disclosure, FTP servers and network application. Several flaws enable unauthenticated remote code execution or sensitive data exposure, posing a significant risk to enterprise security.

Key Findings

• Wing FTP Server (CVE-2025-47812): A critical Remote Code Execution (RCE) vulnerability that enables unauthenticated attackers to execute arbitrary code with root/SYSTEM-level privileges by exploiting a Lua injection flaw.
• Infoblox NetMRI (CVE-2025-32813): A remote unauthenticated command injection flaw that allows an attacker to execute arbitrary commands, potentially leading to unauthorized access.
• Citrix Netscaler ADC (CVE-2025-5777, CVE-2023-4966): A sensitive information disclosure vulnerability, also known as "Citrix Bleed2", that allows the disclosure of memory and subsequent remote access session hijacking.
• Akamai CloudTest (CVE-2025-49493): An XML External Entity (XXE) injection that could lead to read local files on the system by manipulating XML input.

Impact

These vulnerabilities affect critical enterprise infrastructure, from file transfer services and network management appliances to application delivery controllers. The Wing FTP RCE and Infoblox command injection flaws offer direct paths to deep system compromise, while the Citrix "Bleed2" and Akamai XXE vulnerabilities undermine system integrity by enabling session hijacking and sensitive data theft.

Vite 7 ↗ is now supported in the Cloudflare Vite plugin. See the Vite changelog ↗ for a list of changes.

Note that the minimum Node.js versions supported by Vite 7 are 20.19 and 22.12. We continue to support Vite 6 so you do not need to immediately upgrade.

You can now create document-based detection entries in DLP by uploading example documents. Cloudflare will encrypt your documents and create a unique fingerprint of the file. This fingerprint is then used to identify similar documents or snippets within your organization's traffic and stored files.

Key features and benefits:

• Upload documents, forms, or templates: Easily upload .docx and .txt files (up to 10 MB) that contain sensitive information you want to protect.

• Granular control with similarity percentage: Define a minimum similarity percentage (0-100%) that a document must meet to trigger a detection, reducing false positives.

• Comprehensive coverage: Apply these document-based detection entries in:

  • Gateway policies: To inspect network traffic for sensitive documents as they are uploaded or shared.

  • CASB (Cloud Access Security Broker): To scan files stored in cloud applications for sensitive documents at rest.

• Identify sensitive data: This new detection entry type is ideal for identifying sensitive data within completed forms, templates, or even small snippets of a larger document, helping you prevent data exfiltration and ensure compliance.

Once uploaded and processed, you can add this new document entry into a DLP profile and policies to enhance your data protection strategy.

Your real-time applications running over Cloudflare Tunnel are now faster and more reliable. We've completely re-architected the way cloudflared proxies UDP traffic in order to isolate it from other traffic, ensuring latency-sensitive applications like private DNS are no longer slowed down by heavy TCP traffic (like file transfers) on the same Tunnel.

This is a foundational improvement to Cloudflare Tunnel, delivered automatically to all customers. There are no settings to configure — your UDP traffic is already flowing faster and more reliably.

What’s new:

• Faster UDP performance: We've significantly reduced the latency for establishing new UDP sessions, making applications like private DNS much more responsive.
• Greater reliability for mixed traffic: UDP packets are no longer affected by heavy TCP traffic, preventing timeouts and connection drops for your real-time services.

Learn more about running TCP or UDP applications and private networks through Cloudflare Tunnel.

Earlier this year, we announced the launch of the new Terraform v5 Provider. We are aware of the high number of issues ↗ reported by the Cloudflare community related to the v5 release, with 13.5% of resources impacted. We have committed to releasing improvements on a 2 week cadeance to ensure it's stability and relability, including the v5.7 release.

Thank you for continuing to raise issues and please keep an eye on this changelog for more information about upcoming releases.

• Addressed permanent diff bug on Cloudflare Tunnel config
• State is now saved correctly for Zero Trust Access applications
• Exact match is now working as expected within data.cloudflare_zero_trust_access_applications
• cloudflare_zero_trust_access_policy now supports OIDC claims & diff issues resolved
• Self hosted applications with private IPs no longer require a public domain for cloudflare_zero_trust_access_application.
• New resource:
  • cloudflare_zero_trust_tunnel_warp_connector
• Other bug fixes

For a more detailed look at all of the changes, see the changelog ↗ in GitHub.

• #5563: cloudflare_logpull_retention is missing import ↗
• #5608: cloudflare_zero_trust_access_policy in 5.5.0 provider gives error upon apply unexpected new value: .app_count: was cty.NumberIntVal(0), but now cty.NumberIntVal(1) ↗
• #5612: data.cloudflare_zero_trust_access_applications does not exact match ↗
• #5532: cloudflare_zero_trust_access_identity_provider detects changes on every plan ↗
• #5662: cloudflare_zero_trust_access_policy does not support OIDC claims ↗
• #5565: Running Terraform with the cloudflare_zero_trust_access_policy resource results in updates on every apply, even when no changes are made - breaks idempotency ↗
• #5529: cloudflare_zero_trust_access_application: self hosted applications with private ips require public domain ↗

If you have an unaddressed issue with the provider, we encourage you to check the open issues ↗ and open a new one if one does not already exist for what you are experiencing.

We suggest holding on migration to v5 while we work on stabilization of the v5 provider. This will ensure Cloudflare can work ahead and avoid any blocking issues.

If you'd like more information on migrating from v4 to v5, please make use of the migration guide ↗. We have provided automated migration scripts using Grit which simplify the transition, although these do not support implementations which use Terraform modules, so customers making use of modules need to migrate manually. Please make use of terraform plan to test your changes before applying, and let us know if you encounter any additional issues by reporting to our GitHub repository ↗.

This week’s vulnerability analysis highlights emerging web application threats that exploit modern JavaScript behavior and SQL parsing ambiguities. Attackers continue to refine techniques such as attribute overloading and obfuscated logic manipulation to evade detection and compromise front-end and back-end systems.

Key Findings

• XSS – Attribute Overloading: A novel cross-site scripting technique where attackers abuse custom or non-standard HTML attributes to smuggle payloads into the DOM. These payloads evade traditional sanitization logic, especially in frameworks that loosely validate attributes or trust unknown tokens.
• XSS – onToggle Event Abuse: Exploits the lesser-used onToggle event (triggered by elements like <details>) to execute arbitrary JavaScript when users interact with UI elements. This vector is often overlooked by static analyzers and can be embedded in seemingly benign components.

Impact

These vulnerabilities target both user-facing components and back-end databases, introducing potential vectors for credential theft, session hijacking, or full data exfiltration. The XSS variants bypass conventional filters through overlooked HTML behaviors, while the obfuscated SQLi enables attackers to stealthily probe back-end logic, making them especially difficult to detect and block.

Use our brand new onboarding experience for Cloudflare Zero Trust. New and returning users can now engage with a Get Started tab with walkthroughs for setting up common use cases end-to-end.

There are eight brand new onboarding guides in total:

• Securely access a private network (sets up device client and Tunnel)
• Device-to-device / mesh networking (sets up and connects multiple device clients)
• Network to network connectivity (sets up and connects multiple WARP Connectors, makes reference to Magic WAN availability for Enterprise)
• Secure web traffic (sets up device client, Gateway, pre-reqs, and initial policies)
• Secure DNS for networks (sets up a new DNS location and Gateway policies)
• Clientless web access (sets up Access to a web app, Tunnel, and public hostname)
• Clientless SSH access (all the same + the web SSH experience)
• Clientless RDP access (all the same + RDP-in-browser)

Each flow walks the user through the steps to configure the essential elements, and provides a “more details” panel with additional contextual information about what the user will accomplish at the end, along with why the steps they take are important.

Try them out now in the Zero Trust dashboard ↗!

Log Explorer customers can now monitor their data ingestion volume to keep track of their billing. Monthly usage is displayed at the top of the Log Search and Manage Datasets screens in Log Explorer.

You can now expect 3-5× faster indexing in AutoRAG, and with it, a brand new Jobs view to help you monitor indexing progress.

With each AutoRAG, indexing jobs are automatically triggered to sync your data source (i.e. R2 bucket) with your Vectorize index, ensuring new or updated files are reflected in your query results. You can also trigger jobs manually via the Sync API or by clicking “Sync index” in the dashboard.

With the new jobs observability, you can now:

• View the status, job ID, source, start time, duration and last sync time for each indexing job
• Inspect real-time logs of job events (e.g. Starting indexing data source...)
• See a history of past indexing jobs under the Jobs tab of your AutoRAG

This makes it easier to understand what’s happening behind the scenes.

Coming soon: We’re adding APIs to programmatically check indexing status, making it even easier to integrate AutoRAG into your workflows.

Try it out today on the Cloudflare dashboard ↗.

You can use Images to ingest HEIC images and serve them in supported output formats like AVIF, WebP, JPEG, and PNG.

When inputting a HEIC image, dimension and sizing limits may still apply. Refer to our documentation to see limits for uploading to Images or transforming a remote image.

Cloudy, Cloudflare's AI Agent, will now automatically summarize your Access and Gateway block logs.

In the log itself, Cloudy will summarize what occurred and why. This will be helpful for quick troubleshooting and issue correlation.

If you have feedback about the Cloudy summary - good or bad - you can provide that right from the summary itself.

Cloudflare Zero Trust customers can use the App Library to get full visibility over the SaaS applications that they use in their Gateway policies, CASB integrations, and Access for SaaS applications.

App Library, found under My Team, makes information available about all Applications that can be used across the Zero Trust product suite.

You can use the App Library to see:

• How Applications are defined
• Where they are referenced in policies
• Whether they have Access for SaaS configured
• Review their CASB findings and integration status.

Within individual Applications, you can also track their usage across your organization, and better understand user behavior.

We have significantly increased the limits for IP Lists on Enterprise plans to provide greater flexibility and control:

• Total number of lists: Increased from 10 to 1,000.
• Total number of list items: Increased from 10,000 to 500,000.

Limits for other list types and plans remain unchanged. For more details, refer to the lists availability.

This week’s roundup uncovers critical vulnerabilities affecting enterprise VoIP systems, webmail platforms, and a popular JavaScript framework. The risks range from authentication bypass to remote code execution (RCE) and buffer handling flaws, each offering attackers a path to elevate access or fully compromise systems.

Key Findings

• Next.js - Auth Bypass: A newly detected authentication bypass flaw in the Next.js framework allows attackers to access protected routes or APIs without proper authorization, undermining application access controls.
• Fortinet FortiVoice (CVE-2025-32756): A buffer error vulnerability in FortiVoice systems that could lead to memory corruption and potential code execution or service disruption in enterprise telephony environments.
• Roundcube (CVE-2025-49113): A critical RCE flaw allowing unauthenticated attackers to execute arbitrary PHP code via crafted requests, leading to full compromise of mail servers and user inboxes.

Impact

These vulnerabilities affect core business infrastructure, from web interfaces to voice communications and email platforms. The Roundcube RCE and FortiVoice buffer flaw offer potential for deep system access, while the Next.js auth bypass undermines trust boundaries in modern web apps.

Workers now support breakpoint debugging using VSCode's built-in JavaScript Debug Terminals ↗. All you have to do is open a JS debug terminal (Cmd + Shift + P and then type javascript debug) and run wrangler dev (or vite dev) from within the debug terminal. VSCode will automatically connect to your running Worker (even if you're running multiple Workers at once!) and start a debugging session.

In 2023 we announced breakpoint debugging support ↗ for Workers, which meant that you could easily debug your Worker code in Wrangler's built-in devtools (accessible via the [d] hotkey) as well as multiple other devtools clients, including VSCode ↗. For most developers, breakpoint debugging via VSCode is the most natural flow, but until now it's required manually configuring a launch.json file ↗, running wrangler dev, and connecting via VSCode's built-in debugger. Now it's much more seamless!

You can now specify the number of connections your Hyperdrive configuration uses to connect to your origin database.

All configurations have a minimum of 5 connections. The maximum connection count for a Hyperdrive configuration depends on the Hyperdrive limits of your Workers plan.

This feature allows you to right-size your connection pool based on your database capacity and application requirements. You can configure connection counts through the Cloudflare dashboard or API.

Refer to the Hyperdrive configuration documentation for more information.

Browser-based RDP with Cloudflare Access is now available in open beta for all Cloudflare customers. It enables secure, remote Windows server access without VPNs or RDP clients.

With browser-based RDP, you can:

• Control how users authenticate to internal RDP resources with single sign-on (SSO), multi-factor authentication (MFA), and granular access policies.
• Record who is accessing which servers and when to support regulatory compliance requirements and to gain greater visibility in the event of a security event.
• Eliminate the need to install and manage software on user devices. You will only need a web browser.
• Reduce your attack surface by keeping your RDP servers off the public Internet and protecting them from common threats like credential stuffing or brute-force attacks.

To get started, see Connect to RDP in a browser.

We are introducing a new feature of AI Crawl Control — Pay Per Crawl. Pay Per Crawl enables site owners to require payment from AI crawlers every time the crawlers access their content, thereby fostering a fairer Internet by enabling site owners to control and monetize how their content gets used by AI.

For Site Owners:

• Set pricing and select which crawlers to charge for content access
• Manage payments via Stripe
• Monitor analytics on successful content deliveries

For AI Crawler Owners:

• Use HTTP headers to request and accept pricing
• Receive clear confirmations on charges for accessed content

Learn more in the Pay Per Crawl documentation.

We redesigned the AI Crawl Control dashboard to provide more intuitive and granular control over AI crawlers.

• From the new AI Crawlers tab: block specific AI crawlers.
• From the new Metrics tab: view AI Crawl Control metrics.

To get started, explore:

• Manage AI crawlers.
• Analyze AI traffic.

Radar now offers expanded insights into web crawlers, giving you greater visibility into aggregated trends in crawl and refer activity.

We have introduced the following endpoints:

• /bots/crawlers/summary/{dimension}: Returns an overview of crawler HTTP request distributions across key dimensions.
• /bots/crawlers/timeseries_groups/{dimension}: Provides time-series data on crawler request distributions across the same dimensions.

These endpoints allow analysis across the following dimensions:

• user_agent: Parsed data from the User-Agent header.
• referer: Parsed data from the Referer header.
• crawl_refer_ratio: Ratio of HTML page crawl requests to HTML page referrals by platform.

In addition to crawler-specific insights, Radar now provides a broader set of bot endpoints:

• /bots/: Lists all bots.
• /bots/{bot_slug}: Returns detailed metadata for a specific bot.
• /bots/timeseries: Time-series data for bot activity.
• /bots/summary/{dimension}: Returns an overview of bot HTTP request distributions across key dimensions.
• /bots/timeseries_groups/{dimension}: Provides time-series data on bot request distributions across the same dimensions.

These endpoints support filtering and breakdowns by:

• bot: Bot name.
• bot_operator: The organization or entity operating the bot.
• bot_category: Classification of bot type.

The previously available verified_bots endpoints have now been deprecated in favor of this set of bot insights APIs. While current data still focuses on verified bots, we plan to expand support for unverified bot traffic in the future.

Learn more about the new Radar bot and crawler insights in our blog post ↗.

You can now use any of Vite's static asset handling ↗ features in your Worker as well as in your frontend. These include importing assets as URLs, importing as strings and importing from the public directory as well as inlining assets.

Additionally, assets imported as URLs in your Worker are now automatically moved to the client build output.

Here is an example that fetches an imported asset using the assets binding and modifies the response.

// Import the asset URL
// This returns the resolved path in development and production
import myImage from "./my-image.png";

export default {
	async fetch(request, env) {
		// Fetch the asset using the binding
		const response = await env.ASSETS.fetch(new URL(myImage, request.url));
		// Create a new `Response` object that can be modified
		const modifiedResponse = new Response(response.body, response);
		// Add an additional header
		modifiedResponse.headers.append("my-header", "imported-asset");

		// Return the modified response
		return modifiedResponse;
	},
};

Refer to Static Assets in the Cloudflare Vite plugin docs for more info.

The Email Routing platform supports SPF ↗ records and DKIM (DomainKeys Identified Mail) ↗ signatures and honors these protocols when the sending domain has them configured. However, if the sending domain doesn't implement them, we still forward the emails to upstream mailbox providers.

Starting on July 3, 2025, we will require all emails to be authenticated using at least one of the protocols, SPF or DKIM, to forward them. We also strongly recommend that all senders implement the DMARC protocol.

If you are using a Worker with an Email trigger to receive email messages and forward them upstream, you will need to handle the case where the forward action may fail due to missing authentication on the incoming email.

SPAM has been a long-standing issue with email. By enforcing mail authentication, we will increase the efficiency of identifying abusive senders and blocking bad emails. If you're an email server delivering emails to large mailbox providers, it's likely you already use these protocols; otherwise, please ensure you have them properly configured.
