Detailed vulnerability description
The vulnerability allows a remote user to bypass sender restrictions and enqueue system-event text into an active session.
The vulnerability exists due to incorrect authorization in Slack interactive callback handling when processing shared-workspace interactive callbacks before full sender authorization checks. A remote user can send a crafted interactive callback to bypass sender restrictions and enqueue system-event text into an active session.
The issue affects the block_action, view_submission, and view_closed callback flows in shared Slack workspace deployments that rely on allowFrom, DM policy, or channel user allowlists.
