How to Fix GHSA-76xq-58hj-vwm2

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

test-module-a fixed: Latest secure release
npm install test-module-a@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 test-module-a

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-76xq-58hj-vwm2, inspect your project dependencies using npm:

npm ls test-module-a

Analyze the terminal output to locate any version of Test module a 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 test-module-a command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature. In Test module a, 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

All versions of `test-module-a` contain malicious code as a preinstall script. The package fetches all names of npm packages owned by the user and attempts to add another maintainer to every package as a means of package hijacking, ## Recommendation Remove the package from your system. If you own any packages that were compromised please contact npm security immediately at security@npmjs.com. Also enable 2FA for publishing to further secure packages you maintain.
