Administrator session hijacking via unescaped audit log
Published Jul 30, 2026 · Updated Jul 30, 2026
Stored XSS in OpenClaw Dashboard 3.0.0 allows remote attackers to hijack an administrator session via a crafted login username. Failed login handling writes the submitted username verbatim to the audit log, and the notification panel later concatenates it into innerHTML under a CSP that permits inline handlers. Exploitation requires an initialized administrator account and the administrator to open the notification panel; executed script can read the session token and call authenticated endpoints.
