Description

OpenClaw before 2026.3.25 contains a privilege escalation vulnerability in the gateway plugin subagent fallback deleteSession function that uses a synthetic operator.admin runtime scope. Attackers can exploit this by triggering session deletion without a request-scoped client to execute privileged operations with unintended administrative scope.
