How to Fix CVE-2024-25620

To remediate this vulnerability, upgrade all affected Helm.sh/helm/v3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

helm.sh/helm/v3 fixed: 3.14.1 
Upgrade helm.sh/helm/v3 to 3.14.1
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 helm.sh/helm/v3

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-25620, inspect your project dependencies for Helm.sh/helm/v3:

inspect dependencies for helm.sh/helm/v3

Analyze the terminal output to locate any version of Helm.sh/helm/v3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.14.1), 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-23: Relative Path Traversal, where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. In Helm.sh/helm/v3, 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

A Helm contributor discovered a path traversal vulnerability when Helm saves a chart including at download time. ### Impact When either the Helm client or SDK is used to save a chart whose name within the `Chart.yaml` file includes a relative path change, the chart would be saved outside its expected directory based on the changes in the relative path. The validation and linting did not detect the path changes in the name. ### Patches This issue has been resolved in Helm v3.14.1. ### Workarounds Check all charts used by Helm for path changes in their name as found in the `Chart.yaml` file. This includes dependencies. ### Credits Disclosed by Dominykas Blyžė at Nearform Ltd.
