How to Check if You Are Affected

To determine whether your application is affected by GHSA-g4vj-cjjj-v7hg, inspect your project dependencies for NuGet.Packaging:

inspect dependencies for NuGet.Packaging

Analyze the terminal output to locate any version of NuGet.Packaging in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.9.7), 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-345: Insufficient Verification of Data Authenticity, where the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. In NuGet.Packaging, 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.
