OpenClaw: Slack thread context could include messages from non-allowlisted senders
Summary
Before OpenClaw 2026.4.2, Slack thread starter and thread-history context fetched through the API was not filtered by the effective sender allowlist. Messages from non-allowlisted senders could still enter the agent context when an allowlisted user replied in the same thread.
Impact
A Slack deployment that relied on sender allowlists could still feed non-allowlisted thread content into the model context through thread history. This was a sender-access-control bypass on Slack thread context, not a direct channel-auth bypass.
