GHSA-22vc-5pgw-644q — kubeview
CRITICALGHSA-22vc-5pgw-644q is a critical-severity (CVSS 9.8) Missing Authentication vulnerability in github.com/benc-uk/kubeview. 1 public exploit reference exists, so weaponization risk is real. No vendor fix is recorded yet; mitigation options are listed below.
KubeView vulnerable to full cluster takeover due to improper authentication
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

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.
How urgent is this, really
GHSA-22vc-5pgw-644q plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE sits: patch-first territory.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the 50–90% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
KubeView through 0.1.31 allows attackers to obtain control of a Kubernetes cluster because api/scrape/kube-system does not require authentication, and retrieves certificate files that can be used for authentication as kube-admin. NOTE: the vendor's position is that KubeView was a "fun side project and a learning exercise," and not "very secure."

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/benc-uk/kubeview, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of github.com/benc-uk/kubeview has shipped for GHSA-22vc-5pgw-644q yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-22vc-5pgw-644q can be triaged on real exposure rather than presence alone.
Tailored to GHSA-22vc-5pgw-644q. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
How to detect GHSA-22vc-5pgw-644q
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id ghsa-22vc-5pgw-644q -u https://target- Template
- KubeView <=0.1.31 - Information Disclosure
- Severity
- critical
- Impact
- Unauthenticated attackers can access Kubernetes certificate files through the unauthenticated api/scrape/kube-system endpoint, potentially obtaining kube-admin credentials and gaining complete control over the Kubernetes cluster.
- Remediation
- Upgrade KubeView to a version higher than 0.1.31 to mitigate the information disclosure vulnerability (CVE-2022-45933).
