Description
OpenClaw versions prior to 2026.3.1 fail to properly handle authentication bootstrap errors during startup, allowing browser-control routes to remain accessible without authentication. Local processes or loopback-reachable SSRF paths can exploit this to access browser-control routes including evaluate-capable actions without valid credentials.
