3Description
OpenClaw before 2026.3.12 contains an authorization bypass vulnerability where Feishu reaction events with omitted chat_type are misclassified as p2p conversations instead of group chats. Attackers can exploit this misclassification to bypass groupAllowFrom and requireMention protections in group chat reaction-derived events.
Analysis
OpenClaw before version 2026.3.12 permits authorization bypass in Feishu reaction event handling when chat_type parameters are omitted, causing group chat events to be misclassified as peer-to-peer conversations and allowing attackers to circumvent groupAllowFrom and requireMention security controls. Unauthenticated remote attackers can exploit this with low complexity to achieve partial confidentiality and integrity impacts. …
