Description
OpenClaw before 2026.3.25 contains an improper access control vulnerability in the HTTP /sessions/:sessionKey/kill route that allows any bearer-authenticated user to invoke admin-level session termination functions without proper scope validation. Attackers can exploit this by sending authenticated requests to kill arbitrary subagent sessions via the killSubagentRunAdmin function, bypassing ownership and operator scope restrictions.
