  "details": "## Summary\n\nBefore 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.\n\n## Impact\n\nAn 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.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `\u003e= 2026.2.19, \u003c 2026.3.31`\n- Patched versions: `\u003e= 2026.3.31`\n- Latest published npm version: `2026.4.1`\n\n## Fix Commit(s)\n\n- `4d038bb242c11f39e45f6a4bde400e5fd42e4ebf` \u2014 scope webhook replay dedupe per target\n- `7cea7c29705b188b464cc9cdc107c275b94b2a72` \u2014 follow-up hardening to scope replay dedupe by path and account\n\n## Release Process Note\n\nThe 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.\n\nThanks @nexrin for reporting.",
