Description

OpenClaw before 2026.5.18 contains an identity header validation vulnerability allowing local same-host callers to forge trusted-proxy identity headers. Attackers with access to the proxy-facing Gateway port can supply forged identity headers to assume operator identity and potentially escalate privileges.
