Description

OpenClaw before 2026.3.23 contains an insufficient access control vulnerability in the Gateway agent /reset endpoint that allows callers with operator.write permission to reset admin sessions. Attackers with operator.write privileges can invoke /reset or /new messages with an explicit sessionKey to bypass operator.admin requirements and reset arbitrary sessions.
