How to Fix GHSA-v6gv-fg46-h89j

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

put fixed: Latest secure release 
npm install put@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 put

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-v6gv-fg46-h89j, inspect your project dependencies using npm:

npm ls put

Analyze the terminal output to locate any version of Put 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 put 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Put, 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 `put` are vulnerable to Uninitialized Memory Exposure. The package incorrectly calculates the allocated Buffer size and does not trim the bytes written, which may allow attackers to access uninitialized memory containing sensitive data. This vulnerability only affects versions of Node.js <=6.x. ## Recommendation Upgrade your Node.js version or consider using an alternative package.
