Description

OpenClaw affected by Stored XSS in Control UI via unsanitized assistant name/avatar in inline script injection (CVE-2026-27009)

Details

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).
