  • Published2026-11-06
  • WeaknessCWE-79

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

The MCB WordPress plugin through 1.0.0 does not sanitise or escape request header values before storing them and later rendering them in the administrator statistics grid, allowing unauthenticated attackers to store malicious JavaScript that executes in an administrator's browser session when the statistics page is viewed.
