CVE-2026-28485 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. OpenClaw versions 2026.1.5 prior to 2026.2.12 fail to enforce mandatory authentication on the /agent/act browser-control HTTP route, allowing unauthorized local callers to invoke privileged operations. Remote attackers on the local network or local processes can execute arbitrary browser-context actions and access sensitive in-session data by sending requests to unauthenticated endpoints.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
