EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
The Kubernetes kubelet component allows arbitrary command execution via specially crafted gitRepo volumes.This issue affects kubelet: through 1.28.11, from 1.29.0 through 1.29.6, from 1.30.0 through 1.30.2.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | k8s.io/kubernetes | all versions | 1.28.12 |
| 🐹Go | k8s.io/kubernetes | ≥ 1.29.0&&< 1.29.7 | 1.29.7 |
| 🐹Go | k8s.io/kubernetes | ≥ 1.30.0&&< 1.30.3 | 1.30.3 |

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 1.28.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-27wf-5967-98gx 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-27wf-5967-98gx 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-27wf-5967-98gx. 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-27wf-5967-98gx in your dependencies?
O3 detects GHSA-27wf-5967-98gx across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
