High (7.1) in openclaw openclaw. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in openclaw 2026.2.21.
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.
