NVD description
OpenClaw versions prior to 2026.2.26 fail to enforce sender authorization in member and message subtype system event handlers, allowing unauthorized events to be enqueued. Attackers can bypass Slack DM allowlists and per-channel user allowlists by sending system events from non-allowlisted senders through message_changed, message_deleted, and thread_broadcast events.
What to do
- Upgrade OpenClaw to
2026.2.26or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
