Alert meAnalysisAIv1 – Mar 12, 2026
OpenClaw versions prior to 2026.2.14 lack proper Cross-Origin Request Forgery (CSRF) protections on localhost mutation endpoints, allowing malicious websites to trigger unauthorized actions against a victim's local AI assistant instance such as opening tabs, modifying storage, or controlling browser functions. The vulnerability affects the browser control plane through cross-origin requests initiated from the victim's browser context, despite the service's loopback binding. Version 2026.2.14 and later mitigate this by validating Origin/Referer headers and rejecting mutating requests from cross-site origins.

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.

2DescriptionGitHub Advisory
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.
Executive ViewAI
OpenClaw AI assistant installations are vulnerable to cross-origin request forgery attacks that could allow attackers to manipulate data or execute unauthorized actions through browser-based exploitation. This affects any organization deploying OpenClaw prior to version 2026.2.14, potentially compromising sensitive AI assistant configurations and user data.
Apply vendor patch. If immediate patching is not feasible, implement network-level controls to restrict localhost access to trusted internal networks only, disable OpenClaw's browser-facing mutation routes if not operationally critical, and deploy WAF rules to block requests with missing or invalid Origin/Referer headers to localhost endpoints.
