Description

Summary

Before OpenClaw 2026.4.2, Zalo webhook replay dedupe keys were not scoped strongly enough across chat and sender dimensions. Legitimate events from different conversations or senders could collide and be dropped as duplicates.

Impact

Cross-conversation or cross-sender collisions could cause silent message suppression and break bot workflows. This was an availability issue in webhook event processing.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.4.1
  • Patched versions: >= 2026.4.2
  • Latest published npm version: 2026.4.1

Fix Commit(s)

  • ef7c553dd16ee579f1d1a363f5881a99726c1412 — scope Zalo webhook replay dedupe across the missing event dimensions

Release Process Note

The fix is present on main and is staged for OpenClaw 2026.4.2. Publish this advisory after the 2026.4.2 npm release is live.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update openclaw to 2026.4.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rxmx-g7hr-8mx4 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-rxmx-g7hr-8mx4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-rxmx-g7hr-8mx4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
