OpenClaw 2026.1.5 < 2026.2.12 - Missing Authentication in Browser Control HTTP Endpoints
CVSS 4.0
7.5High
Official description
OpenClaw versions 2026.1.5 prior to 2026.2.12 fail to enforce mandatory authentication on the /agent/act browser-control HTTP route, allowing unauthorized local callers to invoke privileged operations. Remote attackers on the local network or local processes can execute arbitrary browser-context actions and access sensitive in-session data by sending requests to unauthenticated endpoints.
