PatchTheCVECVE-2026-117604: Grav from 1.7.53.3 before 1.7.53.6 contains an authorization bypass in Debugger::isDebuggerRequestAuthorized()
CVE-2026-117604 is a high-severity flaw (CVSS 7.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
