State: Published
Severity: 7.5 High
Published: Mar 5, 2026
Updated: Mar 9, 2026
Reserved: Feb 27, 2026

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.
