Critical (9.1) in openclaw openclaw. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in openclaw 2026.4.10.
OpenClaw versions 2026.3.31 before 2026.4.10 contain a privilege escalation vulnerability where heartbeat owner downgrade detection misses local background async exec completion events. Attackers can exploit this by providing untrusted completion content to leave a run in a more privileged context than intended.
