OpenClaw versions 2026.3.31 before 2026.4.10 contain a privilege escalation vulnerability where heartbeat owner downgrad

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.
