GHSA-r6cc-7wj7-gfx2 has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-r6cc-7wj7-gfx2?

GHSA-r6cc-7wj7-gfx2 affects the following packages: github.com/kubernetes-csi/csi-proxy/v2 (Go), github.com/kubernetes-csi/csi-proxy (Go), github.com/kubernetes-csi/csi-proxy (Go), github.com/kubernetes-csi/csi-proxy (Go). Ecosystems affected: Go.

How do I fix GHSA-r6cc-7wj7-gfx2?

Update github.com/kubernetes-csi/csi-proxy/v2 to 2.0.0-alpha.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r6cc-7wj7-gfx2 is resolved across your whole dependency graph.

How do I detect GHSA-r6cc-7wj7-gfx2 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/kubernetes-csi/csi-proxy/v2. 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.

How do I mitigate GHSA-r6cc-7wj7-gfx2 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-r6cc-7wj7-gfx2?

O3 pinpoints whether GHSA-r6cc-7wj7-gfx2 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-r6cc-7wj7-gfx2 actively exploited in the wild?

No public exploit code has been indexed for GHSA-r6cc-7wj7-gfx2 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-r6cc-7wj7-gfx2?

GHSA-r6cc-7wj7-gfx2 has an EPSS (Exploit Prediction Scoring System) score of 2.9%, placing it in the 85th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-r6cc-7wj7-gfx2 published, and has it been updated?

GHSA-r6cc-7wj7-gfx2 was published on November 3, 2023 and was last updated on July 9, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Kubernetes is vulnerable to privilege escalation when a user that can create pods on Windows nodes running kubernetes-csi-proxy may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they include Windows nodes running kubernetes-csi-proxy.
