When browser control started without explicit auth credentials, OpenClaw attempted to bootstrap auth automatically. In affected versions, if that bootstrap step threw an error, startup could continue and expose browser-control routes without authentication.
On affected deployments, a local process (or a loopback-reachable SSRF path) could access browser-control routes, including evaluate-capable actions, without auth.
Startup now fails closed: if bootstrap auth fails and no explicit token/password is configured, browser-control startup aborts.
