What is CVE-2026-44993?

OpenClaw versions prior to 2026.4.20 are vulnerable to a message classification flaw within Feishu card-action callbacks. This vulnerability allows attackers to wrongly classify direct messages as group conversations, enabling them to bypass dmPolicy enforcement. As a result, attackers can exploit card-action triggers in direct message conversations that would typically be restricted, compromising user privacy and security measures in place.
