## WAF Release - 2026-07-17 - Emergency

Jul 17, 2026 

[ WAF ](https://edgetunnel-b2h.pages.dev/waf/) 

This emergency release adds a new managed rule to block active exploitation of a critical remote code execution (RCE) and SQL injection (SQLi) vulnerability found in popular web frameworks.

**Key Findings**

* Generic Frameworks - Unauthenticated RCE: Attackers can execute arbitrary system commands with web server privileges by sending malicious input containing invalid path sequences during request processing.
* Generic Frameworks - SQLi: Attackers can execute unauthorized database queries due to a failure to sanitize input values within request parameters.
