How to Fix GHSA-v82c-5c2q-hx9g

To remediate this vulnerability, upgrade all affected Duplicate Advisory dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/grafana/grafana-operator fixed: Latest secure release 
Upgrade github.com/grafana/grafana-operator to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/grafana/grafana-operator

How to Check if You Are Affected

To determine whether your application is affected by GHSA-v82c-5c2q-hx9g, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for github.com/grafana/grafana-operator

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Duplicate Advisory, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-fcw4-wwqm-m8cf. This link is maintained to preserve external references. ## Original Description We have released version 5.24.0 of the Grafana Operator. This patch includes a CRITICAL 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 metadata: name: "prevent-jsonnet-dashboards" spec: failurePolicy: Fail matchConstraints: resourceRules: - apiGroups: ["grafana.integreatly.org"] apiVersions: ["v1beta1"] operations: ["CREATE", "UPDATE"] resources: ["grafanadashboards", "grafanalibrarypanels"] validations: - expression: "!has(object.spec.jsonnetLib)" --- apiVersion: admissionregistration.k8s.io/v1 kind: ValidatingAdmissionPolicyBinding metadata: name: "prevent-jsonnet-dashboards-clusterwide" spec: policyName: "prevent-jsonnet-dashboards" validationActions: [Deny] ### Acknowledgement We would like to thank Artem Cherezov for responsibly disclosing the vulnerability.
