Description

Summary

Zalo webhook replay cache cross-target messageId scope bypass

Current Maintainer Triage

  • Status: narrow
  • Normalized severity: low
  • Assessment: v2026.3.28 replay dedupe is still keyed too broadly, but the issue should stay scoped to authenticated sibling-target delivery paths rather than arbitrary unauthenticated attackers.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version: 2026.3.31
  • Vulnerable version range: <=2026.3.28
  • Patched versions: >= 2026.3.31
  • First stable tag containing the fix: v2026.3.31

Release Process Note

  • The fix is already present in released version 2026.3.31.
  • This draft looks ready for final maintainer disposition or publication, not additional code-fix work.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.3.31 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hhq4-97c2-p447 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.
