How to Fix GHSA-qpw2-xchm-655q

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

stringstream fixed: 0.0.6 
npm install stringstream@0.0.6
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 stringstream

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-qpw2-xchm-655q, inspect your project dependencies using npm:

npm ls stringstream

Analyze the terminal output to locate any version of Stringstream in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.6), your application is affected.

Note: The npm ls stringstream 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-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In Stringstream, 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 less than 0.0.6 of the Node.js stringstream module are vulnerable to an out-of-bounds read because of allocation of uninitialized buffers when a number is passed in the input stream (when using Node.js 4.x). # WITHDRAWN This is a duplicate of GHSA-mf6x-7mm4-x2g7
