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 2026.4.2 fails to normalize trailing-dot localhost hosts in remote CDP discovery responses, allowing bypass of loopback protections. Attackers can craft hostile discovery responses returning localhost. to retarget authenticated browser control toward localhost endpoints and expose browser state.
