{"cve":"CVE-2026-26317","nvd":{"published":"2026-02-19T22:16:47.270","modified":"2026-06-17T10:26:04.873","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L","score":7.1},"cwes":["CWE-352"],"references":["https://github.com/openclaw/openclaw/commit/b566b09f81e2b704bf9398d8d97d5f7a90aa94c3","https://github.com/openclaw/openclaw/releases/tag/v2026.2.14","https://github.com/openclaw/openclaw/security/advisories/GHSA-3fqr-4cg8-h96q"],"products":["openclaw:openclaw"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-26317","score":0.00164,"percentile":0.05635,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3fqr-4cg8-h96q","url":"https://osv.dev/vulnerability/GHSA-3fqr-4cg8-h96q","summary":"OpenClaw affected by cross-site request forgery (CSRF) through loopback browser mutation endpoints","modified":"2026-02-20T16:52:03.831109Z","packages":[{"ecosystem":"npm","name":"openclaw","purl":"pkg:npm/openclaw","ranges":["<2026.2.14"],"fixed":["2026.2.14"]},{"ecosystem":"npm","name":"clawdbot","purl":"pkg:npm/clawdbot","ranges":["<=2026.1.24-3"],"fixed":[]}]}],"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).
