| Summary | OpenClaw: Zalo replay dedupe cache could suppress events across authenticated webhook targets ## Summary Before OpenClaw 2026.3.31, the Zalo webhook replay-dedupe cache was shared across authenticated webhook targets and keyed too broadly. In multi-account deployments, a replay seen on one account could suppress a legitimate event on another account if `event_name` and `message_id` matched. ## Impact An attacker who controlled one authenticated Zalo webhook path in a multi-account gateway deployment could cause silent message suppression on a different Zalo account sharing that gateway. This was an availability issue; it did not provide cross-account authentication or data access. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `>= 2026.2.19, < 2026.3.31` - Patched versions: `>= 2026.3.31` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `4d038bb242c11f39e45f6a4bde400e5fd42e4ebf` — scope webhook replay dedupe per target - `7cea7c29705b188b464cc9cdc107c275b94b2a72` — follow-up hardening to scope replay dedupe by path and account ## Release Process Note The initial fix shipped in OpenClaw `2026.3.31` on March 31, 2026. The current published npm release `2026.4.1` from April 1, 2026 also contains follow-up hardening for the same surface. Thanks @nexrin for reporting. |
