We’ve launched two powerful new tools to make the GraphQL Analytics API more accessible:
The new GraphQL API Explorer ↗ helps you build, test, and run queries directly in your browser. Features include:
- In-browser schema documentation to browse available datasets and fields
- Interactive query editor with autocomplete and inline documentation
- A "Run in GraphQL API Explorer" button to execute example queries from our docs
- Seamless OAuth authentication — no manual setup required
MCP Servers let you use natural language tools like Claude to generate structured queries against your data. See our blog post ↗ for details on how they work and which servers are available. The new GraphQL MCP server ↗ helps you discover and generate useful queries for the GraphQL Analytics API. With this server, you can:
- Explore what data is available to query
- Generate and refine queries using natural language, with one-click links to run them in the API Explorer
- Build dashboards and visualizations from structured query outputs
Example prompts include:
- “Show me HTTP traffic for the last 7 days for example.com”
- “What GraphQL node returns firewall events?”
- “Can you generate a link to the Cloudflare GraphQL API Explorer with a pre-populated query and variables?”
We’re continuing to expand these tools, and your feedback helps shape what’s next. Explore the documentation to learn more and get started.
In Cloudflare Workers, you can now attach an event listener to
Requestobjects, using thesignalproperty ↗. This allows you to perform tasks when the request to your Worker is canceled by the client. To use this feature, you must set theenable_request_signalcompatibility flag.You can use a listener to perform cleanup tasks or write to logs before your Worker's invocation ends. For example, if you run the Worker below, and then abort the request from the client, a log will be written:
index.js export default {async fetch(request, env, ctx) {// This sets up an event listener that will be called if the client disconnects from your// worker.request.signal.addEventListener("abort", () => {console.log("The request was aborted!");});const { readable, writable } = new IdentityTransformStream();sendPing(writable);return new Response(readable, {headers: { "Content-Type": "text/plain" },});},};async function sendPing(writable) {const writer = writable.getWriter();const enc = new TextEncoder();for (;;) {// Send 'ping' every second to keep the connection aliveawait writer.write(enc.encode("ping\r\n"));await scheduler.wait(1000);}}index.ts export default {async fetch(request, env, ctx): Promise<Response> {// This sets up an event listener that will be called if the client disconnects from your// worker.request.signal.addEventListener('abort', () => {console.log('The request was aborted!');});const { readable, writable } = new IdentityTransformStream();sendPing(writable);return new Response(readable, { headers: { 'Content-Type': 'text/plain' } });},} satisfies ExportedHandler<Env>;async function sendPing(writable: WritableStream): Promise<void> {const writer = writable.getWriter();const enc = new TextEncoder();for (;;) {// Send 'ping' every second to keep the connection aliveawait writer.write(enc.encode('ping\r\n'));await scheduler.wait(1000);}}For more information see the
Requestdocumentation.
Earlier this year, we announced the launch of the new Terraform v5 Provider. Unlike the earlier Terraform providers, v5 is automatically generated based on the OpenAPI Schemas for our REST APIs. Since launch, we have seen an unexpectedly high number of issues ↗ reported by customers. These issues currently impact about 15% of resources. We have been working diligently to address these issues across the company, and have released the v5.5.0 release which includes a number of bug fixes. Please keep an eye on this changelog for more information about upcoming releases.
- Broad fixes across resources with recurring diffs, including, but not limited to:
cloudflare_zero_trust_gateway_policycloudflare_zero_trust_access_applicationcloudflare_zero_trust_tunnel_cloudflared_routecloudflare_zone_settingcloudflare_rulesetcloudflare_page_rule
- Zone settings can be re-applied without client errors
- Page rules conversion errors are fixed
- Failure to apply changes to
cloudflare_zero_trust_tunnel_cloudflared_route - Other bug fixes
For a more detailed look at all of the changes, see the changelog ↗ in GitHub.
- #5304: Importing cloudflare_zero_trust_gateway_policy invalid attribute filter value ↗
- #5303: cloudflare_page_rule import does not set values for all of the fields in terraform state ↗
- #5178: cloudflare_page_rule Page rule creation with redirect fails ↗
- #5336: cloudflare_turnstile_wwidget not able to update ↗
- #5418: cloudflare_cloud_connector_rules: Provider returned invalid result object after apply ↗
- #5423: cloudflare_zone_setting: "Invalid value for zone setting always_use_https" ↗
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.
If you are evaluating a move 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 planto test your changes before applying, and let us know if you encounter any additional issues by reporting to our GitHub repository ↗.- Broad fixes across resources with recurring diffs, including, but not limited to:
This week's analysis covers four vulnerabilities, with three rated critical due to their Remote Code Execution (RCE) potential. One targets a high-traffic frontend platform, while another targets a popular content management system. These detections are now part of the Cloudflare Managed Ruleset in Block mode.
Key Findings
- Commvault Command Center (CVE-2025-34028) exposes an unauthenticated RCE via insecure command injection paths in the web UI. This is critical due to its use in enterprise backup environments.
- BentoML (CVE-2025-27520) reveals an exploitable vector where serialized payloads in model deployment APIs can lead to arbitrary command execution. This targets modern AI/ML infrastructure.
- Craft CMS (CVE-2024-56145) allows RCE through template injection in unauthenticated endpoints. It poses a significant risk for content-heavy websites with plugin extensions.
- Apache HTTP Server (CVE-2024-38475) discloses sensitive server config data due to misconfigured
mod_proxybehavior. While not RCE, this is useful for pre-attack recon.
Impact
These newly detected vulnerabilities introduce critical risk across modern web stacks, AI infrastructure, and content platforms: unauthenticated RCEs in Commvault, BentoML, and Craft CMS enable full system compromise with minimal attacker effort.
Apache HTTPD information leak can support targeted reconnaissance, increasing the success rate of follow-up exploits. Organizations using these platforms should prioritize patching and monitor for indicators of exploitation using updated WAF detection rules.

To access the new overview, log in to your Cloudflare Zero Trust dashboard ↗ and find Analytics in the side navigation bar.
You can now create Durable Objects using Python Workers. A Durable Object is a special kind of Cloudflare Worker which uniquely combines compute with storage, enabling stateful long-running applications which run close to your users. For more info see here.
You can define a Durable Object in Python in a similar way to JavaScript:
Python from workers import DurableObject, Response, WorkerEntrypointfrom urllib.parse import urlparseclass MyDurableObject(DurableObject):def __init__(self, ctx, env):self.ctx = ctxself.env = envdef fetch(self, request):result = self.ctx.storage.sql.exec("SELECT 'Hello, World!' as greeting").one()return Response(result.greeting)class Default(WorkerEntrypoint):async def fetch(self, request):url = urlparse(request.url)id = env.MY_DURABLE_OBJECT.idFromName(url.path)stub = env.MY_DURABLE_OBJECT.get(id)greeting = await stub.fetch(request.url)return greetingDefine the Durable Object in your Wrangler configuration file:
JSONC {"durable_objects": {"bindings": [{"name": "MY_DURABLE_OBJECT","class_name": "MyDurableObject"}]}}TOML [[durable_objects.bindings]]name = "MY_DURABLE_OBJECT"class_name = "MyDurableObject"Then define the storage backend for your Durable Object:
JSONC {"migrations": [{"tag": "v1", // Should be unique for each entry"new_sqlite_classes": [ // Array of new classes"MyDurableObject"]}]}TOML [[migrations]]tag = "v1"new_sqlite_classes = [ "MyDurableObject" ]Then test your new Durable Object locally by running
wrangler dev:Terminal window npx wrangler devConsult the Durable Objects documentation for more details.
You can now safely open email attachments to view and investigate them.
What this means is that messages now have a Attachments section. Here, you can view processed attachments and their classifications (for example, Malicious, Suspicious, Encrypted). Next to each attachment, a Browser Isolation icon allows your team to safely open the file in a clientless, isolated browser with no risk to the analyst or your environment.
To use this feature, you must:
- Turn on Allow users to open a remote browser without the device client in your Zero Trust settings.
- Have Browser Isolation (BISO) seats assigned.
For more details, refer to our setup guide.
Some attachment types may not render in Browser Isolation. If there is a file type that you would like to be opened with Browser Isolation, reach out to your Cloudflare contact.
This feature is available across these Email security packages:
- Advantage
- Enterprise
- Enterprise + PhishGuard

Hyperdrive has been approved for FedRAMP Authorization and is now available in the FedRAMP Marketplace ↗.
FedRAMP is a U.S. government program that provides standardized assessment and authorization for cloud products and services. As a result of this product update, Hyperdrive has been approved as an authorized service to be used by U.S. federal agencies at the Moderate Impact level.
For detailed information regarding FedRAMP and its implications, please refer to the official FedRAMP documentation for Cloudflare ↗.
We are adding source origin restrictions to the Media Transformations beta. This allows customers to restrict what sources can be used to fetch images and video for transformations. This feature is the same as --- and uses the same settings as --- Image Transformations sources.
When transformations is first enabled, the default setting only allows transformations on images and media from the same website or domain being used to make the transformation request. In other words, by default, requests to
example.com/cdn-cgi/mediacan only reference originals onexample.com.
Adding access to other sources, or allowing any source, is easy to do in the Transformations tab under Stream. Click each domain enabled for Transformations and set its sources list to match the needs of your content. The user making this change will need permission to edit zone settings.
For more information, learn about Transforming Videos.
Remote Browser Isolation (RBI) now supports SAML HTTP-POST bindings, enabling seamless authentication for SSO-enabled applications that rely on POST-based SAML responses from Identity Providers (IdPs) within a Remote Browser Isolation session. This update resolves a previous limitation that caused
405errors during login and improves compatibility with multi-factor authentication (MFA) flows.With expanded support for major IdPs like Okta and Azure AD, this enhancement delivers a more consistent and user-friendly experience across authentication workflows. Learn how to set up Remote Browser Isolation.
You can now create DNS policies to manage outbound traffic for an expanded list of applications. This update adds support for 273 new applications, giving you more control over your organization's outbound traffic.
With this update, you can:
- Create DNS policies for a wider range of applications
- Manage outbound traffic more effectively
- Improve your organization's security and compliance posture
For more information on creating DNS policies, see our DNS policy documentation.
You can now configure custom word lists to enforce case sensitivity. This setting supports flexibility where needed and aims to reduce false positives where letter casing is critical.
You can now publish messages to Cloudflare Queues directly via HTTP from any service or programming language that supports sending HTTP requests. Previously, publishing to queues was only possible from within Cloudflare Workers. You can already consume from queues via Workers or HTTP pull consumers, and now publishing is just as flexible.
Publishing via HTTP requires a Cloudflare API token with
Queues Editpermissions for authentication. Here's a simple example:Terminal window curl "https://api.cloudflare.com/client/v4/accounts/<account_id>/queues/<queue_id>/messages" \-X POST \-H 'Authorization: Bearer <api_token>' \--data '{ "body": { "greeting": "hello", "timestamp": "2025-07-24T12:00:00Z"} }'You can also use our SDKs for TypeScript, Python, and Go.
To get started with HTTP publishing, check out our step-by-step example and the full API documentation in our API reference.
You can now use IP, Autonomous System (AS), and Hostname custom lists to route traffic to Snippets and Cloud Connector, giving you greater precision and control over how you match and process requests at the edge.
In Snippets, you can now also match on Bot Score and WAF Attack Score, unlocking smarter edge logic for everything from request filtering and mitigation to tarpitting and logging.
What’s new:
- Custom lists matching – Snippets and Cloud Connector now support user-created IP, AS, and Hostname lists via dashboard or Lists API. Great for shared logic across zones.
- Bot Score and WAF Attack Score – Use Cloudflare’s intelligent traffic signals to detect bots or attacks and take advanced, tailored actions with just a few lines of code.
These enhancements unlock new possibilities for building smarter traffic workflows with minimal code and maximum efficiency.
Learn more in the Snippets and Cloud Connector documentation.
You can now safely open links in emails to view and investigate them.
From Investigation, go to View details, and look for the Links identified section. Next to each link, the Cloudflare dashboard will display an Open in Browser Isolation icon which allows your team to safely open the link in a clientless, isolated browser with no risk to the analyst or your environment. Refer to Open links to learn more about this feature.
To use this feature, you must:
- Turn on Allow users to open a remote browser without the device client in your Zero Trust settings.
- Have Browser Isolation (RBI) seats assigned.
For more details, refer to our setup guide.
This feature is available across these Email security packages:
- Advantage
- Enterprise
- Enterprise + PhishGuard
Enterprise customers can now choose the geographic location from which a URL scan is performed — either via Security Center in the Cloudflare dashboard or via the URL Scanner API.
This feature gives security teams greater insight into how a website behaves across different regions, helping uncover targeted, location-specific threats.
What’s new:
- Location Picker: Select a location for the scan via Security Center → Investigate in the dashboard or through the API.
- Region-aware scanning: Understand how content changes by location — useful for detecting regionally tailored attacks.
- Default behavior: If no location is set, scans default to the user’s current geographic region.
Learn more in the Security Center documentation.
We have upgraded WAF Payload Logging to enhance rule diagnostics and usability:
- Targeted logging: Logs now capture only the specific portions of requests that triggered WAF rules, rather than entire request segments.
- Visual highlighting: Matched content is visually highlighted in the UI for faster identification.
- Enhanced context: Logs now include surrounding context to make diagnostics more effective.
Payload Logging is available to all Enterprise customers. If you have not used Payload Logging before, check how you can get started.
Note: The structure of the
encrypted_matched_datafield in Logpush has changed fromMap<Field, Value>toMap<Field, {Before: bytes, Content: Value, After: bytes}>. If you rely on this field in your Logpush jobs, you should review and update your processing logic accordingly.
FinalizationRegistry ↗ is now available in Workers. You can opt-in using the
enable_weak_refcompatibility flag.This can reduce memory leaks when using WebAssembly-based Workers, which includes Python Workers and Rust Workers. The FinalizationRegistry works by enabling toolchains such as Emscripten ↗ and wasm-bindgen ↗ to automatically free WebAssembly heap allocations. If you are using WASM and seeing Exceeded Memory errors and cannot determine a cause using memory profiling, you may want to enable the FinalizationRegistry.
For more information refer to the
enable_weak_refcompatibility flag documentation.
You can now send DLP forensic copies to third-party storage for any HTTP policy with an
AlloworBlockaction, without needing to include a DLP profile. This change increases flexibility for data handling and forensic investigation use cases.By default, Gateway will send all matched HTTP requests to your configured DLP Forensic Copy jobs.
Cloudflare Load Balancing now supports UDP (Layer 4) and ICMP (Layer 3) health monitors for private endpoints. This makes it simple to track the health and availability of internal services that don’t respond to HTTP, TCP, or other protocol probes.
- Set up ICMP ping monitors to check if your private endpoints are reachable.
- Use UDP monitors for lightweight health checks on non-TCP workloads, such as DNS, VoIP, or custom UDP-based services.
- Gain better visibility and uptime guarantees for services running behind Private Network Load Balancing, without requiring public IP addresses.
This enhancement is ideal for internal applications that rely on low-level protocols, especially when used in conjunction with Cloudflare Tunnel, WARP, and Magic WAN to create a secure and observable private network.
Learn more about Private Network Load Balancing or view the full list of supported health monitor protocols.
