How to Fix GHSA-gqf6-75v8-vr26

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

bin-links fixed: 1.1.5 
npm install bin-links@1.1.5
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 bin-links

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-gqf6-75v8-vr26, inspect your project dependencies using npm:

npm ls bin-links

Analyze the terminal output to locate any version of Bin links in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.5), your application is affected.

Note: The npm ls bin-links 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 General Security Weakness. In Bin links, 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

Versions of `bin-links` prior to 1.1.5 are vulnerable to an Arbitrary File Write. The package fails to restrict access to folders outside of the intended `node_modules` folder through the `bin` field. This allows attackers to create arbitrary files in the system. Note it is not possible to overwrite files that already exist. ## Recommendation Upgrade to version 1.1.5 or later.
