Description
OpenClaw versions prior to 2026.2.21 contain an improper URL scheme validation vulnerability in the assertBrowserNavigationAllowed() function that allows authenticated users with browser-tool access to navigate to file:// URLs. Attackers can exploit this by accessing local files readable by the OpenClaw process user through browser snapshot and extraction actions to exfiltrate sensitive data.
