How severe is CVE-2020-8568?

CVE-2020-8568 has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2020-8568?

CVE-2020-8568 affects the following packages: sigs.k8s.io/secrets-store-csi-driver (Go). Ecosystems affected: Go.

How do I fix CVE-2020-8568?

Update sigs.k8s.io/secrets-store-csi-driver to 0.0.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-8568 is resolved across your whole dependency graph.

How do I detect CVE-2020-8568 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sigs.k8s.io/secrets-store-csi-driver, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2020-8568 if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is CVE-2020-8568 actively exploited in the wild?

No public exploit code has been indexed for CVE-2020-8568 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 CVE-2020-8568?

CVE-2020-8568 has an EPSS (Exploit Prediction Scoring System) score of 1.3%, placing it in the 71th 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.

What type of vulnerability is CVE-2020-8568?

Description

Kubernetes Secrets Store CSI Driver versions v0.0.15 and v0.0.16 allow an attacker who can modify a SecretProviderClassPodStatus/Status resource the ability to write content to the host filesystem and sync file contents to Kubernetes Secrets. This includes paths under var/lib/kubelet/pods that contain other Kubernetes Secrets.
