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).","published":"2026-02-19T23:25:41.111Z","modified":"2026-08-12T03:51:24.588681084Z","cvss":{"score":5.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.15"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/3b4096e02e7e335f99f5986ec1bd566e90b14a7e","label":"openclaw/openclaw@3b4096e"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.15"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27009.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-37gc-85xm-2ww6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27009"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/3b4096e02e7e335f99f5986ec1bd566e90b14a7e"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/adc818db4a4b3b8d663e7674ef20436947514e1b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:24.588681084Z"}}
