Summary
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.
Risk Assessment
An attacker can access local resources and browser data of the victim, leading to leakage of sensitive information and potential session hijacking.
Recommendation
Update OpenClaw to version 2026.4.2 or later, which normalizes trailing-dot hostnames.
