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).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:N","score":5.8},"cwes":["CWE-79"],"references":["https://github.com/openclaw/openclaw/commit/3b4096e02e7e335f99f5986ec1bd566e90b14a7e","https://github.com/openclaw/openclaw/commit/adc818db4a4b3b8d663e7674ef20436947514e1b","https://github.com/openclaw/openclaw/releases/tag/v2026.2.15","https://github.com/openclaw/openclaw/security/advisories/GHSA-37gc-85xm-2ww6"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-27009","score":0.00264,"percentile":0.18324,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-37gc-85xm-2ww6","url":"https://osv.dev/vulnerability/GHSA-37gc-85xm-2ww6","summary":"OpenClaw affected by Stored XSS in Control UI via unsanitized assistant name/avatar in inline script injection","modified":"2026-02-20T17:02:59.385901Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.2.15"],"fixed":["2026.2.15"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
