## WAF Release - 2026-07-14

Jul 14, 2026 

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

This release introduces new rules targeting critical infrastructure vulnerabilities. These include an unauthenticated memory disclosure flaw in Citrix NetScaler ADC and Gateway (CVE-2026-8451) and a high-severity pre-authentication remote code execution (RCE) vulnerability in Progress Kemp LoadMaster (CVE-2026-8037).

**Key Findings**

* CVE-2026-8451: An insufficient input validation vulnerability affects Citrix NetScaler ADC and NetScaler Gateway appliances configured as a SAML Identity Provider (IdP). Remote, unauthenticated attackers can exploit this flaw by sending malformed requests to trigger a memory overread, allowing them to leak chunks of sensitive data from adjacent appliance memory.
* CVE-2026-8037: A critical OS command injection vulnerability in Progress Kemp LoadMaster load balancers allows unauthenticated remote attackers to achieve remote code execution (RCE).
