How to Fix GHSA-mwp6-j9wf-968c

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

generator-jhipster fixed: 6.3.0 
npm install generator-jhipster@6.3.0
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 generator-jhipster

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-mwp6-j9wf-968c, inspect your project dependencies using npm:

npm ls generator-jhipster

Analyze the terminal output to locate any version of Generator jhipster in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.3.0), your application is affected.

Note: The npm ls generator-jhipster 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 Generator jhipster, 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

Account takeover and privilege escalation is possible in applications generated by generator-jhipster before 6.3.0. This is due to a vulnerability in the generated java classes: CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) Generated applications must be manually patched, following instructions in the release notes: https://www.jhipster.tech/2019/09/13/jhipster-release-6.3.0.html
