CVE-2026-35673Network attack vector

Protected content access via blocked-tab reuse

Published May 29, 2026 · Updated May 29, 2026

SSRF policy bypass in OpenClaw before 2026.4.29 allows remote authenticated users to inspect blocked private-network tab content. The browser debug and export routes accept references to already-open tabs without reapplying the SSRF policy that blocked their private-network navigation. Exploitation requires the affected feature to be enabled and reachable, low-privileged route access, an existing blocked tab, and user interaction; it exposes protected tab content and derived exports.
