How to Fix CVE-2022-41376

To remediate this vulnerability, upgrade all affected Metro4 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

metro4 fixed: Latest secure release 
npm install metro4@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: 

npm ls metro4

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-41376, inspect your project dependencies using npm:

npm ls metro4

Analyze the terminal output to locate any version of Metro4 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: The npm ls metro4 command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
