Duplicate Advisory: OpenClaw's Signal reaction-only status events could, in limited cases, be enqueued before access checks

Original Description

OpenClaw versions prior to 2026.2.25 contain an access control vulnerability in signal reaction notification handling that allows unauthorized senders to enqueue status events before authorization checks are applied. Attackers can exploit the reaction-only event path in event-handler.ts to queue signal reaction status lines for sessions without proper DM or group access validation.
