GHSA-h7wq-jj8r-qm7p
HIGHGHSA-h7wq-jj8r-qm7p is a high-severity (CVSS 7.7) Improper Input Validation vulnerability in k8s.io/kubernetes. O3 Security confirms whether GHSA-h7wq-jj8r-qm7p is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Blast Radius
k8s.io/kubernetesReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
A flaw was found in kube-controller-manager. This issue occurs when the initial application of a HPA config YAML lacking a .spec.behavior.scaleUp block causes a denial of service due to KCM pods going into restart churn.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | k8s.io/kubernetes | all versions | 1.27.0-alpha.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/kubernetes. 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/kubernetes to 1.27.0-alpha.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h7wq-jj8r-qm7p 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-h7wq-jj8r-qm7p 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-h7wq-jj8r-qm7p. 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-h7wq-jj8r-qm7p in your dependencies?
O3 detects GHSA-h7wq-jj8r-qm7p across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
