How to Fix GHSA-q4h9-46xg-m3x9

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

@openzeppelin/contracts-upgradeable fixed: 4.3.2 
npm install @openzeppelin/contracts-upgradeable@4.3.2
Verify Direct and Transitive Dependencies

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

npm ls @openzeppelin/contracts-upgradeable

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-q4h9-46xg-m3x9, inspect your project dependencies using npm:

npm ls @openzeppelin/contracts-upgradeable

Analyze the terminal output to locate any version of @openzeppelin/contracts upgradeable in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.3.2), your application is affected.

Note: The npm ls @openzeppelin/contracts-upgradeable command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
