How to Fix GHSA-3p92-886g-qxpq

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

floody fixed: 0.1.1 
npm install floody@0.1.1
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 floody

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-3p92-886g-qxpq, inspect your project dependencies using npm:

npm ls floody

Analyze the terminal output to locate any version of Floody in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.1), your application is affected.

Note: The npm ls floody 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-201: Insertion of Sensitive Information Into Sent Data, where the code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor. In Floody, 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 `floody` before 0.1.1 are vulnerable to remote memory exposure. .write(number)` in the affected `floody` versions passes a number to Buffer constructor, appending a chunk of uninitialized memory. Proof of Concept: ``` var f = require('floody')(process.stdout); f.write(USERSUPPLIEDINPUT); 'f.stop(); ## Recommendation Update to version 0.1.1 or later.
