GHSA-p239-93f7-h6xf
GHSA-p239-93f7-h6xf is a security vulnerability in swagger-ui. O3 Security confirms whether GHSA-p239-93f7-h6xf is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Cross-Site Scripting in swagger-ui
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.
swagger-uinpmDescription
Affected versions of swagger-ui contain a cross-site scripting vulnerability in the key names of a specific nested object in the JSON document.
Proof of Concept
The vulnerable object structure is:
{
"definitions": {
"arbitraryVal": {
"properties": {
"<INJECTABLE_KEY_NAME>": "LoremIpsum"
}
}
}
}
Malicious JSON documents can be loaded in by providing a URL to them in the url query string parameter.
Recommendation
Update to version 2.2.1 or later.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | swagger-ui | all versions | 2.2.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for swagger-ui. 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 swagger-ui to 2.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-p239-93f7-h6xf 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-p239-93f7-h6xf 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-p239-93f7-h6xf. 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-p239-93f7-h6xf in your dependencies?
O3 detects GHSA-p239-93f7-h6xf across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
