CVE-2026-26317Network attack vector

Unauthorized browser state changes via unvalidated cross-origin requests

Published Feb 19, 2026 · Updated Feb 19, 2026

CSRF in OpenClaw before 2026.2.14 allows remote attackers to alter local browser-control state through cross-origin requests. The loopback mutation routes accepted POST, PUT, PATCH, and DELETE requests without validating Origin, Referer, or Sec-Fetch-Site. A victim must visit a malicious website while the unauthenticated browser control service is reachable in that browser context; resulting actions include opening tabs, changing cookies or storage, and starting or stopping the browser.
