OpenClaw before 2026.3.31 contains a scope bypass vulnerability in webhook replay cache deduplication that allows authenticated attackers to replay messages across sibling targets using the same messageId. Attackers can exploit overly broad cache keying to bypass replay protection and deliver duplicate webhook messages to unintended targets.
