CVE-2026-117604
Grav from 1.7.53.3 before 1.7.53.6 contains an authorization bypass in Debugger::isDebuggerRequestAuthorized() that allows unauthenticated visitors to read /clockwork/ profiler data via a loopback REMOTEADDR fallback. Behind a same-host reverse proxy, remote requests appear as loopback, letting attackers read stored records including administrator plaintext passwords and configuration credentials.
