How to Fix GHSA-r2gr-fhmr-66c5

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

socket.io-file fixed: Latest secure release 
npm install socket.io-file@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 socket.io-file

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-r2gr-fhmr-66c5, inspect your project dependencies using npm:

npm ls socket.io-file

Analyze the terminal output to locate any version of Duplicate Advisory 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 socket.io-file command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Source Advisory Statement

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-6495-8jvh-f28x. This link is maintained to preserve external references. ## Original Description "The socket.io-file package through 2.0.31 for Node.js relies on client-side validation of file types, which allows remote attackers to execute arbitrary code by uploading an executable file via a modified JSON name field. NOTE: This vulnerability only affects products that are no longer supported by the maintainer."
