Description
cc-connect through 1.5.0 fails to enforce per-user allowlist filtering in the onCardAction handler for Feishu interactive card callbacks. Attackers can dispatch agent commands by triggering card actions in admitted chats, bypassing the per-user access controls that protect the text message handler.
