Which packages are affected by GHSA-fcw4-wwqm-m8cf?

GHSA-fcw4-wwqm-m8cf affects the following packages: github.com/grafana/grafana-operator/v5 (Go), github.com/grafana/grafana-operator (Go). Ecosystems affected: Go.

How do I fix GHSA-fcw4-wwqm-m8cf?

Update github.com/grafana/grafana-operator/v5 to 5.24.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fcw4-wwqm-m8cf is resolved across your whole dependency graph.

How do I detect GHSA-fcw4-wwqm-m8cf in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/grafana/grafana-operator/v5. 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-fcw4-wwqm-m8cf 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-fcw4-wwqm-m8cf?

O3 pinpoints whether GHSA-fcw4-wwqm-m8cf 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-fcw4-wwqm-m8cf actively exploited in the wild?

No public exploit code has been indexed for GHSA-fcw4-wwqm-m8cf 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-fcw4-wwqm-m8cf?

GHSA-fcw4-wwqm-m8cf has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 29th 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 GHSA-fcw4-wwqm-m8cf?

GHSA-fcw4-wwqm-m8cf is classified as Path Traversal (CWE-22). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-fcw4-wwqm-m8cf published, and has it been updated?

GHSA-fcw4-wwqm-m8cf was published on June 19, 2026 and was last updated on June 25, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

We have released version 5.24.0 of the Grafana Operator. This patch includes a MODERATE severity security fix for a path traversal/privilege escalation vulnerability in the Grafana Operator.

Summary

The Grafana Operator supports loading dashboards & library panels using the jsonnet data templating language. The jsonnet expression is evaluated in the context of the operator manager pod.

Impact

It is possible for a malicious user who can create Dashboard or LibraryPanel resources for a Grafana instance to obtain the Kubernetes service account token of the Grafana Operator manager.

Affected versions

All Grafana Operator versions <= 5.23

Solutions and mitigations

All installations should be upgraded as soon as possible.

As a workaround, the following ValidatingAdmissionPolicy prevent the creation or modification of jsonnet based resources:

apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicy

  name: "prevent-jsonnet-dashboards"
