Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-200.
Summary
Grav from 1.7.53.3 before 1.7.53.6 contains an authorization bypass in Debugger::isDebuggerRequestAuthorized() that trusts a loopback REMOTE_ADDR fallback. Behind a same-host reverse proxy, remote requests appear as loopback, so an unauthenticated visitor can read stored /__clockwork/ profiler records (CWE-200). These records can include administrator plaintext passwords and configuration credentials.
