How to Fix GHSA-g74r-ffvr-5q9f

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

concat-stream fixed: 1.5.2 
npm install concat-stream@1.5.2
concat-stream fixed: 1.4.11 
npm install concat-stream@1.4.11
concat-stream fixed: 1.3.2 
npm install concat-stream@1.3.2
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 concat-stream

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-g74r-ffvr-5q9f, inspect your project dependencies using npm:

npm ls concat-stream

Analyze the terminal output to locate any version of Concat stream in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.5.2), your application is affected.

Note: The npm ls concat-stream 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 Concat stream, 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 `concat-stream` before 1.5.2 are vulnerable to memory exposure if userp provided input is passed into `write()` Versions <1.3.0 are not affected due to not using unguarded Buffer constructor. ## Recommendation Update to version 1.5.2, 1.4.11, 1.3.2 or later. If you are unable to update make sure user provided input into the `write()` function is not a number.
