Title
OpenClaw 2026.2.19 through 2026.3.30 - Webhook Replay Dedupe Cache Event Suppression via Shared Authentication
Summary
OpenClaw versions 2026.2.19 before 2026.3.31 contain an improper cache isolation vulnerability in the Zalo webhook replay-dedupe mechanism that is shared across authenticated webhook targets. Attackers controlling one authenticated Zalo webhook path in multi-account deployments can suppress legitimate events on different accounts by matching event_name and message_id parameters.
