OpenClaw before 2026.4.2 contains an insufficient scope vulnerability in Zalo webhook replay dedupe keys that allows legitimate events from different conversations or senders to collide. Attackers can exploit weak deduplication scoping to cause silent message suppression and disrupt bot workflows across chat sessions.
Add your gear to cvedb and we'll alert you only when openclaw ships something exploited.
