GHSA-3cw3-5vxw-g2h3 is a high-severity (CVSS 7.3) CWE-346 vulnerability in openclaw. O3 Security confirms whether GHSA-3cw3-5vxw-g2h3 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
OpenClaw: CLI Remote Onboarding Persists Unauthenticated Discovery Endpoint and Exfiltrates Gateway Credentials
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
openclawnpmDescription
Summary
Remote onboarding accepted discovered gateway endpoints without an explicit trust confirmation before persisting the remote URL and connection details.
Impact
A malicious or spoofed discovery endpoint could steer onboarding toward an attacker-controlled gateway and capture future gateway credentials or traffic.
Affected Component
src/commands/onboard-remote.ts
Fixed Versions
- Affected:
<= 2026.3.24 - Patched:
>= 2026.3.28 - Latest stable
2026.3.28contains the fix.
Fix
Fixed by commit d6affb17d8 (CLI: confirm discovered remote gateways before saving config).

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update openclaw to 2026.3.28 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3cw3-5vxw-g2h3 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 pinpoints whether GHSA-3cw3-5vxw-g2h3 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-3cw3-5vxw-g2h3. 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-3cw3-5vxw-g2h3 in your dependencies?
O3 detects GHSA-3cw3-5vxw-g2h3 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
