{"id":"CVE-2026-26317","aliases":["GHSA-3fqr-4cg8-h96q"],"url":"https://o3.security/vulnerability/CVE-2026-26317","summary":"OpenClaw affected by cross-site request forgery (CSRF) through loopback browser mutation endpoints","details":"OpenClaw is a personal AI assistant. Prior to 2026.2.14, browser-facing localhost mutation routes accepted cross-origin browser requests without explicit Origin/Referer validation. Loopback binding reduces remote exposure but does not prevent browser-initiated requests from malicious origins. A malicious website can trigger unauthorized state changes against a victim's local OpenClaw browser control plane (for example opening tabs, starting/stopping the browser, mutating storage/cookies) if the browser control service is reachable on loopback in the victim's browser context. Starting in version 2026.2.14, mutating HTTP methods (POST/PUT/PATCH/DELETE) are rejected when the request indicates a non-loopback Origin/Referer (or `Sec-Fetch-Site: cross-site`). Other mitigations include enabling browser control auth (token/password) and avoid running with auth disabled.","published":"2026-02-19T21:34:27.786Z","modified":"2026-08-12T03:51:20.480571675Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.14"},{"ecosystem":"npm","name":"clawdbot","fixedVersion":null}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/b566b09f81e2b704bf9398d8d97d5f7a90aa94c3","label":"openclaw/openclaw@b566b09"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.14"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26317.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-3fqr-4cg8-h96q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26317"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/b566b09f81e2b704bf9398d8d97d5f7a90aa94c3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:20.480571675Z"}}
