Description

OpenClaw before 2026.4.14 contains an improper access control vulnerability in browser snapshot, screenshot, and tab routes that fail to consistently validate the final browser target after navigation. Authenticated callers can bypass SSRF restrictions to expose internal or disallowed page content by exploiting route-driven navigation without proper policy re-validation.
