You can now see the exact cache key generated for any request directly in Cloudflare Trace. This visibility helps you troubleshoot cache hits and misses, and verify that your Custom Cache Keys — configured via Cache Rules or Page Rules — are working as intended.
Previously, diagnosing caching behavior required inferring the key from configuration settings. Now, you can confirm that your custom logic for headers, query strings, and device types is correctly applied.
Access Trace via the dashboard or API, either manually for ad-hoc debugging or automated as part of your quality-of-service monitoring.
If you have a Cache Rule that segments content based on a specific cookie (for example,
user_region), run a Trace with that cookie present to confirm theuser_regionvalue appears in the resulting cache key.The Trace response includes the cache key in the
cacheobject:{"step_name": "request","type": "cache","matched": true,"public_name": "Cache Parameters","cache": {"key": {"zone_id": "023e105f4ecef8ad9ca31a8372d0c353","scheme": "https","host": "example.com","uri": "/images/hero.jpg"},"key_string": "023e105f4ecef8ad9ca31a8372d0c353::::https://example.com/images/hero.jpg:::::"}}To learn more, refer to the Trace documentation and our guide on Custom Cache Keys.
Enable automatic tracing on your Workers, giving you detailed metadata and timing information for every operation your Worker performs.
Tracing helps you identify performance bottlenecks, resolve errors, and understand how your Worker interacts with other services on the Workers platform. You can now answer questions like:
- Which calls are slowing down my application?
- Which queries to my database take the longest?
- What happened within a request that resulted in an error?
You can now:
- View traces alongside your logs in the Workers Observability dashboard
- Export traces (and correlated logs) to any OTLP-compatible destination ↗, such as Honeycomb, Sentry or Grafana, by configuring a tracing destination in the Cloudflare dashboard ↗
- Analyze and query across span attributes (operation type, status, duration, errors)

Magic WAN now supports Automatic Return Routing (ARR), allowing customers to configure Magic on-ramps (IPsec/GRE/CNI) to learn the return path for traffic flows without requiring static routes.
Key benefits:
- Route-less mode: Static or dynamic routes are optional when using ARR.
- Overlapping IP space support: Traffic originating from customer sites can use overlapping private IP ranges.
- Symmetric routing: Return traffic is guaranteed to use the same connection as the original on-ramp.
This feature is currently in beta and requires the new Unified Routing mode (beta).
For configuration details, refer to Configure Automatic Return Routing.
Magic WAN Connector now allows you to designate a specific WAN port for breakout traffic, giving you deterministic control over the egress path for latency-sensitive applications.
With this feature, you can:
- Pin breakout traffic for specific applications to a preferred WAN port.
- Ensure critical traffic (such as Zoom or Teams) always uses your fastest or most reliable connection.
- Benefit from automatic failover to standard WAN port priority if the preferred port goes down.
This is useful for organizations with multiple ISP uplinks who need predictable egress behavior for performance-sensitive traffic.
For configuration details, refer to Designate WAN ports for breakout apps.
We have previously added new application categories to better reflect their content and improve HTTP traffic management: refer to Changelog. While the new categories are live now, we want to ensure you have ample time to review and adjust any existing rules you have configured against old categories. The remapping of existing applications into these new categories will be completed by January 30, 2026. This timeline allows you a dedicated period to:
- Review the new category structure.
- Identify any policies you have that target the older categories.
- Adjust your rules to reference the new, more precise categories before the old mappings change. Once the applications have been fully remapped by January 30, 2026, you might observe some changes in the traffic being mitigated or allowed by your existing policies. We encourage you to use the intervening time to prepare for a smooth transition.

We're excited to announce that Log Explorer users can now cancel queries that are currently running.
This new feature addresses a common pain point: waiting for a long, unintended, or misconfigured query to complete before you can submit a new, correct one. With query cancellation, you can immediately stop the execution of any undesirable query, allowing you to quickly craft and submit a new query, significantly improving your investigative workflow and productivity within Log Explorer.
We're excited to announce a new feature in Log Explorer that significantly enhances how you analyze query results: the Query results distribution chart.
This new chart provides a graphical distribution of your results over the time window of the query. Immediately after running a query, you will see the distribution chart above your result table. This visualization allows Log Explorer users to quickly spot trends, identify anomalies, and understand the temporal concentration of log events that match their criteria. For example, you can visually confirm if a spike in traffic or errors occurred at a specific time, allowing you to focus your investigation efforts more effectively. This feature makes it faster and easier to extract meaningful insights from your vast log data.
The chart will dynamically update to reflect the logs matching your current query.
This week highlights enhancements to detection signatures improving coverage for vulnerabilities in Adobe Commerce and Magento Open Source, linked to CVE-2025-54236.

Workers, including those using Durable Objects and Browser Rendering, may now process WebSocket messages up to 32 MiB in size. Previously, this limit was 1 MiB.
This change allows Workers to handle use cases requiring large message sizes, such as processing Chrome Devtools Protocol messages.
For more information, please see the Durable Objects startup limits.
We've raised the Cloudflare Workflows account-level limits for all accounts on the Workers paid plan:
- Instance creation rate increased from 100 workflow instances per 10 seconds to 100 instances per second
- Concurrency limit increased from 4,500 to 10,000 workflow instances per account
These increases mean you can create new instances up to 10x faster, and have more workflow instances concurrently executing. To learn more and get started with Workflows, refer to the getting started guide.
If your application requires a higher limit, fill out the Limit Increase Request Form or contact your account team. Please refer to Workflows pricing for more information.
Two-factor authentication (2FA) is one of the best ways to protect your account from the risk of account takeover. Cloudflare has offered phishing resistant 2FA options including hardware based keys (for example, a Yubikey) and app based TOTP (time-based one-time password) options which use apps like Google or Microsoft's Authenticator app. Unfortunately, while these solutions are very secure, they can be lost if you misplace the hardware based key, or lose the phone which includes that app. The result is that users sometimes get locked out of their accounts and need to contact support.
Today, we are announcing the addition of email as a 2FA factor for all Cloudflare accounts. Email 2FA is in wide use across the industry as a least common denominator for 2FA because it is low friction, loss resistant, and still improves security over username/password login only. We also know that most commercial email providers already require 2FA, so your email address is usually well protected already.
You can now enable email 2FA on the Cloudflare dashboard:
- Go to Profile at the top right corner.
- Select Authentication.
- Under Two-Factor Authentication, select Set up.
Cloudflare is critical infrastructure, and you should protect it as such. Review the following best practices and make sure you are doing your part to secure your account:
- Use a unique password for every website, including Cloudflare, and store it in a password manager like 1Password or Keeper. These services are cross-platform and simplify the process of managing secure passwords.
- Use 2FA to make it harder for an attacker to get into your account in the event your password is leaked.
- Store your backup codes securely. A password manager is the best place since it keeps the backup codes encrypted, but you can also print them and put them somewhere safe in your home.
- If you use an app to manage your 2FA keys, enable cloud backup, so that you don't lose your keys in the event you lose your phone.
- If you use a custom email domain to sign in, configure SSO.
- If you use a public email domain like Gmail or Hotmail, you can also use social login with Apple, GitHub, or Google to sign in.
- If you manage a Cloudflare account for work:
- Have at least two administrators in case one of them unexpectedly leaves your company.
- Use SCIM to automate permissions management for members in your Cloudflare account.
As Cloudflare's platform has grown, so has the need for precise, role-based access control. We’ve redesigned the Member Management experience in the Dashboard to help administrators more easily discover, assign, and refine permissions for specific principals.
Refreshed member invite flow
We overhauled the Invite Members UI to simplify inviting users and assigning permissions.
Refreshed Members Overview Page
We've updated the Members Overview Page to clearly display:
- Member 2FA status
- Which members hold Super Admin privileges
- API access settings per member
- Member onboarding state (accepted vs pending invite)
New Member Permission Policies Details View
We've created a new member details screen that shows all permission policies associated with a member; including policies inherited from group associations to make it easier for members to understand the effective permissions they have.
Improved Member Permission Workflow
We redesigned the permission management experience to make it faster and easier for administrators to review roles and grant access.
Account-scoped Policies Restrictions Relaxed
Previously, customers could only associate a single account-scoped policy with a member. We've relaxed this restriction, and now Administrators can now assign multiple account-scoped policies to the same member; bringing policy assignment behavior in-line with user-groups and providing greater flexibility in managing member permissions.

Cloudflare now provides two new request fields in the Ruleset engine that let you make decisions based on whether a request used TCP and the measured TCP round-trip time between the client and Cloudflare. These fields help you understand protocol usage across your traffic and build policies that respond to network performance. For example, you can distinguish TCP from QUIC traffic or route high latency requests to alternative origins when needed.
Field Type Description cf.edge.client_tcpBoolean Indicates whether the request used TCP. A value of true means the client connected using TCP instead of QUIC. cf.timings.client_tcp_rtt_msecNumber Reports the smoothed TCP round-trip time between the client and Cloudflare in milliseconds. For example, a value of 20 indicates roughly twenty milliseconds of RTT. Example filter expression:
cf.edge.client_tcp && cf.timings.client_tcp_rtt_msec < 100More information can be found in the Rules language fields reference.
This week’s release introduces a new detection signature that enhances coverage for a critical vulnerability in Oracle E-Business Suite, tracked as CVE-2025-61884.
Key Findings
The flaw is easily exploitable and allows an unauthenticated attacker with network access to compromise Oracle Configurator, which can grant access to sensitive resources and configuration data. The affected versions include 12.2.3 through 12.2.14.
Impact
Successful exploitation of CVE-2025-61884 may result in unauthorized access to critical business data or full exposure of information accessible through Oracle Configurator. Administrators are strongly advised to apply vendor's patches and recommended mitigations to reduce this exposure.

- Click it to instantly open the latest preview URL
- Matches the same experience you're familiar with from Pages
Cloudflare Access for private hostname applications can now secure traffic on all ports and protocols.
Previously, applying Zero Trust policies to private applications required the application to use HTTPS on port
443and support Server Name Indicator (SNI).This update removes that limitation. As long as the application is reachable via a Cloudflare off-ramp, you can now enforce your critical security controls — like single sign-on (SSO), MFA, device posture, and variable session lengths — to any private application. This allows you to extend Zero Trust security to services like SSH, RDP, internal databases, and other non-HTTPS applications.
For example, you can now create a self-hosted application in Access for
ssh.testapp.localrunning on port22. You can then build a policy that only allows engineers in your organization to connect after they pass an SSO/MFA check and are using a corporate device.This feature is generally available across all plans.
AI Search now supports reranking for improved retrieval quality and allows you to set the system prompt directly in your API requests.
You can now enable reranking to reorder retrieved documents based on their semantic relevance to the user’s query. Reranking helps improve accuracy, especially for large or noisy datasets where vector similarity alone may not produce the optimal ordering.
You can enable and configure reranking in the dashboard or directly in your API requests:
JavaScript const answer = await env.AI.autorag("my-autorag").aiSearch({query: "How do I train a llama to deliver coffee?",model: "@cf/meta/llama-3.3-70b-instruct-fp8-fast",reranking: {enabled: true,model: "@cf/baai/bge-reranker-base"}});Previously, system prompts could only be configured in the dashboard. You can now define them directly in your API requests, giving you per-query control over behavior. For example:
JavaScript // Dynamically set query and system prompt in AI Searchasync function getAnswer(query, tone) {const systemPrompt = `You are a ${tone} assistant.`;const response = await env.AI.autorag("my-autorag").aiSearch({query: query,system_prompt: systemPrompt});return response;}// Example usageconst query = "What is Cloudflare?";const tone = "friendly";const answer = await getAnswer(query, tone);console.log(answer);Learn more about Reranking and System Prompt in AI Search.
Cloudflare CASB (Cloud Access Security Broker) now supports two new granular roles to provide more precise access control for your security teams:
- Cloudflare CASB Read: Provides read-only access to view CASB findings and dashboards. This role is ideal for security analysts, compliance auditors, or team members who need visibility without modification rights.
- Cloudflare CASB: Provides full administrative access to configure and manage all aspects of the CASB product.
These new roles help you better enforce the principle of least privilege. You can now grant specific members access to CASB security findings without assigning them broader permissions, such as the Super Administrator or Administrator roles.
To enable Data Loss Prevention (DLP), scans in CASB, account members will need the Cloudflare Zero Trust role.
You can find these new roles when inviting members or creating API tokens in the Cloudflare dashboard under Manage Account > Members.
To learn more about managing roles and permissions, refer to the Manage account members and roles documentation.
To give you precision and flexibility while creating policies to block unwanted traffic, we are introducing new, more granular application categories in the Gateway product.
We have added the following categories to provide more precise organization and allow for finer-grained policy creation, designed around how users interact with different types of applications:
- Business
- Education
- Entertainment & Events
- Food & Drink
- Health & Fitness
- Lifestyle
- Navigation
- Photography & Graphic Design
- Travel
The new categories are live now, but we are providing a transition period for existing applications to be fully remapped to these new categories.
The full remapping will be completed by January 30, 2026.
We encourage you to use this time to:
- Review the new category structure.
- Identify and adjust any existing HTTP policies that reference older categories to ensure a smooth transition.
For more information on creating HTTP policies, refer to Applications and app types.
