Description
A security vulnerability has been discovered in Kubernetes windows nodes that could allow a user with the ability to query a node's '/logs' endpoint to execute arbitrary commands on the host. This CVE affects only Windows worker nodes. Your worker node is vulnerable to this issue if it is running one of the affected versions listed below.

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 1.29.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vv39-3w5q-974q 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-vv39-3w5q-974q 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-vv39-3w5q-974q. 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-vv39-3w5q-974q in your dependencies?
O3 detects GHSA-vv39-3w5q-974q across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
