GHSA-r39h-4c2p-3jxp is a high-severity (CVSS 7.8) remote code execution vulnerability in openclaw. A fix is available for openclaw — see the affected versions and patch details below.
OpenClaw vulnerable to arbitrary code execution via attacker-controlled setup-api.js loaded from cwd during env-key resolution
Exploitation Status
No confirmed exploitation observed yet
- 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.

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-r39h-4c2p-3jxp 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
OpenClaw's bundled plugin setup resolver could fall back to process.cwd() while resolving provider setup metadata. If a user ran an OpenClaw command from an attacker-controlled repository containing extensions/<plugin>/setup-api.js, OpenClaw could load and execute that JavaScript during ordinary provider/model status resolution.
Impact
This is arbitrary JavaScript execution in the OpenClaw process under the current user account. A malicious repository could run code when the user executed commands such as provider/model inspection from that directory. The issue does not require gateway network exposure, but it does require user interaction: the user must run OpenClaw from a directory containing the attacker-controlled setup file.

[email protected], tagv2026.4.23
Fix
OpenClaw now resolves bundled setup fallbacks only from the canonical package/repository root and no longer includes process.cwd() as a trusted setup-api search root. A regression test verifies that a workspace-local extensions/<plugin>/setup-api.js is not loaded through provider setup resolution.
Fix Commit(s)
993781e6e6eaf50f033cfc3e3bf4f47059740707(fix(plugins): ignore cwd setup-api fallback)
Severity
Severity remains high because successful exploitation allows arbitrary code execution under the user running OpenClaw. The CVSS vector is local/user-interaction scoped rather than network-only because the victim must run OpenClaw from an attacker-controlled directory.

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 2026.4.23 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r39h-4c2p-3jxp 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-r39h-4c2p-3jxp can be triaged on real exposure rather than presence alone.
Tailored to GHSA-r39h-4c2p-3jxp. 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-r39h-4c2p-3jxp in your dependencies?
O3 Security finds GHSA-r39h-4c2p-3jxp across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
