How to Fix GHSA-6qqf-vvcr-7qrv

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

generate-password fixed: 1.4.1 
npm install generate-password@1.4.1
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 generate-password

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-6qqf-vvcr-7qrv, inspect your project dependencies using npm:

npm ls generate-password

Analyze the terminal output to locate any version of Generate password in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.1), your application is affected.

Note: The npm ls generate-password 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-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG), where the product uses a pseudo-random number generator (prng) in a security context, but the prng's algorithm is not cryptographically strong. In Generate password, 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

Affected versions of generate-password generate random values that are biased towards certain characters depending on the chosen character sets. This may result in guessable passwords. ## Recommendation Update to version 1.4.1 or later.
