OpenClaw: Heartbeat owner downgrade missed untrusted webhook wake events
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.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-g2hm-779g-vm32.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-g2hm-779g-vm32 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
openclawnpmDescription
Summary
Heartbeat owner downgrade missed untrusted webhook wake events.
Affected Packages / Versions
- Package:
openclaw - Ecosystem: npm
- Affected versions:
>= 2026.4.7 < 2026.4.14 - Patched versions:
>= 2026.4.14
Impact
Heartbeat owner downgrade logic could skip webhook wake events carrying untrusted content, preserving owner-like execution context where the run should have been downgraded.
Technical Details
The fix includes wake and hook event reasons in owner-downgrade inspection and forces downgrade for untrusted hook wake events.
Fix
The issue was fixed in #66031. The first stable tag containing the fix is v2026.4.14, and [email protected] includes the fix.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update openclaw to 2026.4.14 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g2hm-779g-vm32 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-g2hm-779g-vm32 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-g2hm-779g-vm32. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-g2hm-779g-vm32 in your dependencies?
O3 Security finds GHSA-g2hm-779g-vm32 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
