Exploitation Status

No confirmed exploitation observed yet

  • CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
  • A successful exploit gives an attacker total control of the affected component, not partial access.
  • CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description

Summary

The Zalo webhook handler applied request rate limiting only after webhook authentication succeeded. Requests with an invalid secret returned 401 but did not count against the rate limiter, allowing repeated secret guesses without triggering 429.

Impact

This made brute-force guessing materially easier for weak but policy-compliant webhook secrets. Once the secret was guessed, an attacker could submit forged Zalo webhook traffic.

Affected versions

openclaw <= 2026.3.11

Patch

Fixed in openclaw 2026.3.12. Rate limiting now applies before successful authentication is required, closing the pre-auth brute-force gap. Users should update to 2026.3.12 or later and prefer strong webhook secrets.

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 2026.3.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5m9r-p9g7-679c 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-5m9r-p9g7-679c can be triaged on real exposure rather than presence alone.

Tailored to GHSA-5m9r-p9g7-679c. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
