Cloudflare WAF protects WordPress applications from two high-severity vulnerabilities

Cloudflare has implemented new Web Application Firewall (WAF) protections to address two critical vulnerabilities in WordPress, namely an Unauthenticated Remote Code Execution (RCE) vulnerability in the REST API and a related SQL Injection vulnerability. These vulnerabilities, present in WordPress versions 6.8 and later, were disclosed to Cloudflare by the WordPress security team before public release, allowing for preemptive deployment of protective rules effective from July 17, 2026. While Cloudflare's protections mitigate risks for sites with proxied traffic, they are not a substitute for applying the official WordPress patches released in version 7.0.2 and relevant backports. WordPress has classified these issues as high-severity and is automatically updating affected sites, though verification of updates is still recommended. Cloudflare has introduced specific rules to detect and block requests exploiting these vulnerabilities, with monitoring and adjustments planned as necessary to address evolving threats. The collaboration between WordPress and Cloudflare aims to enhance security for users before vulnerabilities were publicly exposed.
