NVD Description

Note: Versions mentioned in the description apply only to the upstream openclaw package and not the openclaw package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

OpenClaw before 2026.4.10 contains a server-side request forgery vulnerability in browser navigation policy that allows attackers to bypass hostname validation through DNS rebinding attacks. Attackers can exploit inconsistent hostname resolution between validation and actual network requests to pivot to internal resources via unallowlisted hostname URLs.
