What is 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 REMOTE_ADDR fallback. Behind a same-host reverse proxy, remote requests appear as loopback, letting attackers read stored records including administrator plaintext passwords and configuration credentials.
