Lifecycle Timeline
4DescriptionGitHub Advisory
OpenClaw is a personal AI assistant. Prior to version 2026.2.15, a atored XSS issue in the OpenClaw Control UI when rendering assistant identity (name/avatar) into an inline <script> tag without script-context-safe escaping. A crafted value containing </script> could break out of the script tag and execute attacker-controlled JavaScript in the Control UI origin. Version 2026.2.15 removed inline script injection and serve bootstrap config from a JSON endpoint and added a restrictive Content Security Policy for the Control UI (script-src 'self', no inline scripts).
AnalysisAI
OpenClaw versions prior to 2026.2.15 contain a stored XSS vulnerability in the Control UI where unsanitized assistant identity values (name/avatar) are injected into inline script tags, allowing authenticated attackers with high privileges to break out of the script context and execute arbitrary JavaScript. Public exploit code exists for this vulnerability. The issue has been remediated in version 2026.2.15 through removal of inline scripts and implementation of a restrictive Content Security Policy.
