1. ### [WAF Release - 2025-07-28](https://edgetunnel-b2h.pages.dev/changelog/post/2025-07-28-waf-release/)  
[ WAF ](https://edgetunnel-b2h.pages.dev/waf/)  
This week’s update spotlights several vulnerabilities across Apache Tomcat, MongoDB, and Fortinet FortiWeb. Several flaws related with a memory leak in Apache Tomcat can lead to a denial-of-service attack. Additionally, a code injection flaw in MongoDB's Mongoose library allows attackers to bypass security controls to access restricted data.

**Key Findings**

  * Fortinet FortiWeb (CVE-2025-25257): An improper neutralization of special elements used in a SQL command vulnerability in Fortinet FortiWeb versions allows an unauthenticated attacker to execute unauthorized SQL code or commands.
  * Apache Tomcat (CVE-2025-31650): A improper Input Validation vulnerability in Apache Tomcat that could create memory leak when incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request.
  * MongoDB (CVE-2024-53900, CVE:CVE-2025-23061): Improper use of `$where` in match and a nested `$where` filter with a `populate()` match in Mongoose can lead to search injection.

**Impact**  
These vulnerabilities target user-facing components, web application servers, and back-end databases. A SQL injection flaw in Fortinet FortiWeb can lead to data theft or system compromise. A separate issue in Apache Tomcat involves a memory leak from improper input validation, which could be exploited for a denial-of-service (DoS) attack. Finally, a vulnerability in MongoDB's Mongoose library allows attackers to bypass security filters and access unauthorized data through malicious search queries.

1. ### [Faster, more reliable UDP traffic for Cloudflare Tunnel](https://edgetunnel-b2h.pages.dev/changelog/post/2025-07-15-udp-improvements/)  
[ Cloudflare Tunnel ](https://edgetunnel-b2h.pages.dev/tunnel/)[ Cloudflare Tunnel for SASE ](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-tunnel/)  
Your real-time applications running over [Cloudflare Tunnel](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/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.

1. ### [WAF Release - 2025-07-14](https://edgetunnel-b2h.pages.dev/changelog/post/2025-07-14-waf-release/)  
[ WAF ](https://edgetunnel-b2h.pages.dev/waf/)  
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.

1. ### [More flexible fallback handling — Custom Errors now support fetching assets returned with 4xx or 5xx status codes](https://edgetunnel-b2h.pages.dev/changelog/post/2025-06-09-custom-errors-fetch-4xx-5xx-assets/)  
[ Rules ](https://edgetunnel-b2h.pages.dev/rules/)  
[Custom Errors](https://edgetunnel-b2h.pages.dev/rules/custom-errors/) can now fetch and store [assets](https://edgetunnel-b2h.pages.dev/rules/custom-errors/create-rules/#create-a-custom-error-asset-dashboard) and [error pages](https://edgetunnel-b2h.pages.dev/rules/custom-errors/#error-pages) from your origin even if they are served with a 4xx or 5xx HTTP status code — previously, only 200 OK responses were allowed.

**What’s new:**

  * You can now upload error pages and error assets that return error status codes (for example, 403, 500, 502, 503, 504) when fetched.
  * These assets are stored and minified at the edge, so they can be reused across multiple Custom Error rules without triggering requests to the origin.  
This is especially useful for retrieving error content or downtime banners from your backend when you can’t override the origin status code.

You can now use the [cf.worker.upstream\_zone](https://edgetunnel-b2h.pages.dev/ruleset-engine/rules-language/fields/reference/cf.worker.upstream%5Fzone/) field in [Transform Rules](https://edgetunnel-b2h.pages.dev/rules/transform/) to control rule execution based on whether a request originates from [Workers](https://edgetunnel-b2h.pages.dev/workers/), including subrequests issued by Workers in other zones.  
![Match Workers subrequests by upstream zone in Transform Rules](https://edgetunnel-b2h.pages.dev/_astro/transform-rule-subrequest-matching.BeUBEN67_wWefn.webp)  

**What's new:**

  * `cf.worker.upstream_zone` is now supported in Transform Rules expressions.
  * Skip or apply logic conditionally when handling [Workers subrequests](https://edgetunnel-b2h.pages.dev/workers/platform/limits/#subrequests).  
For example, to add a header when the subrequest comes from another zone:  
Text in **Expression Editor** (replace `myappexample.com` with your domain):  
```txt  
(cf.worker.upstream_zone != "" and cf.worker.upstream_zone != "myappexample.com")  
```  
Selected operation under **Modify request header**: _Set static_

**Header name**: `X-External-Workers-Subrequest`

**Value**: `1`  
This gives you more granular control in how you handle incoming requests for your zone.

1. ### [WAF Release - 2025-05-19](https://edgetunnel-b2h.pages.dev/changelog/post/2025-05-19-waf-release/)  
[ WAF ](https://edgetunnel-b2h.pages.dev/waf/)  
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_proxy` behavior. 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.

1. ### [Custom Errors are now Generally Available](https://edgetunnel-b2h.pages.dev/changelog/post/2025-04-24-custom-errors-ga/)  
[ Rules ](https://edgetunnel-b2h.pages.dev/rules/)  
[Custom Errors](https://edgetunnel-b2h.pages.dev/rules/custom-errors/) are now generally available for all paid plans — bringing a unified and powerful experience for customizing error responses at both the zone and account levels.  
You can now manage **Custom Error Rules**, **Custom Error Assets**, and redesigned **Error Pages** directly from the Cloudflare dashboard. These features let you deliver tailored messaging when errors occur, helping you maintain brand consistency and improve user experience — whether it’s a 404 from your origin or a security challenge from Cloudflare.  
What's new:

  * **Custom Errors are now GA** – Available on all paid plans and ready for production traffic.
  * **UI for Custom Error Rules and Assets** – Manage your zone-level rules from the Rules > Overview and your zone-level assets from the Rules > Settings tabs.
  * **Define inline content or upload assets** – Create custom responses directly in the rule builder, upload new or reuse previously stored assets.
  * **Refreshed UI and new name for Error Pages** – Formerly known as “Custom Pages,” Error Pages now offer a cleaner, more intuitive experience for both zone and account-level configurations.
  * **Powered by Ruleset Engine** – Custom Error Rules support [conditional logic](https://edgetunnel-b2h.pages.dev/ruleset-engine/rules-language/) and override Error Pages for 500 and 1000 class errors, as well as errors originating from your origin or [other Cloudflare products](https://edgetunnel-b2h.pages.dev/ruleset-engine/reference/phases-list/). You can also configure [Response Header Transform Rules](https://edgetunnel-b2h.pages.dev/rules/transform/response-header-modification/) to add, change, or remove HTTP headers from responses returned by Custom Error Rules.  
Learn more in the [Custom Errors documentation](https://edgetunnel-b2h.pages.dev/rules/custom-errors/).

1. ### [WAF Release - 2025-04-22](https://edgetunnel-b2h.pages.dev/changelog/post/2025-04-22-waf-release/)  
[ WAF ](https://edgetunnel-b2h.pages.dev/waf/)  
Each of this week's rule releases covers a distinct CVE, with half of the rules targeting Remote Code Execution (RCE) attacks. Of the 6 CVEs covered, four were scored as critical, with the other two scored as high.  
When deciding which exploits to tackle, Cloudflare tunes into the attackers' areas of focus. Cloudflare's network intelligence provides a unique lens into attacker activity – for instance, through the volume of blocked requests related with CVE exploits after updating WAF Managed Rules with new detections.  
From this week's releases, one indicator that RCE is a "hot topic" attack type is the fact that the Oracle PeopleSoft RCE rule accounts for half of all of the new rule matches. This rule patches CVE-2023-22047, a high-severity vulnerability in the Oracle PeopleSoft suite that allows unauthenticated attackers to access PeopleSoft Enterprise PeopleTools data through remote code execution. This is particularly concerning because of the nature of the data managed by PeopleSoft – this can include payroll records or student profile information. This CVE, along with five others, are addressed with the latest detection update to WAF Managed Rules.
