What is CVE-2026-32895?

OpenClaw versions before 2026.2.26 contain a vulnerability that allows unauthorized senders to enqueue system events. This occurs due to insufficient enforcement of sender authorization in the member and message subtype system event handlers. As a result, attackers can manipulate Slack direct message allowlists and per-channel user allowlists by injecting system events via methods like message_changed, message_deleted, and thread_broadcast. This poses a significant risk, allowing potential abuse of the messaging framework.
