CVE-2026-35638 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. OpenClaw before 2026.3.22 contains a privilege escalation vulnerability in the Control UI that allows unauthenticated sessions to retain self-declared privileged scopes without device identity verification. Attackers can exploit the device-less allow path in the trusted-proxy mechanism to maintain elevated permissions by declaring arbitrary scopes, bypassing device identity requirements.. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
