GHSA-242m-6h72-7hgp
MEDIUMGHSA-242m-6h72-7hgp is a medium-severity (CVSS 4.8) vulnerability in k8s.io/ingress-nginx. O3 Security confirms whether GHSA-242m-6h72-7hgp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
A security issue was discovered in ingress-nginx where attacker-provided data are included in a filename by the ingress-nginx Admission Controller feature, resulting in directory traversal within the container. This could result in denial of service, or when combined with other vulnerabilities, limited disclosure of Secret objects from the cluster.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | k8s.io/ingress-nginx | all versions | 1.11.5 |
| 🐹Go | k8s.io/ingress-nginx | ≥ 1.12.0-beta.0&&< 1.12.1 | 1.12.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for k8s.io/ingress-nginx. 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 k8s.io/ingress-nginx to 1.11.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-242m-6h72-7hgp 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-242m-6h72-7hgp 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-242m-6h72-7hgp. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
