CVE-2026-109325
HIGH 8.7Grav from 2.0.22 before 2.1.7 contains an authentication bypass vulnerability in the Clockwork profiler that trusts loopback REMOTE_ADDR values. Unauthenticated attackers behind a same-host HTTP proxy can read profiler records exposing system and plugin configuration, secrets, request metadata, and queries.
Severe if exploited (CVSS 8.7), but no known exploitation and low modeled probability. Patch on a normal cadence.
