How to Fix GHSA-5v7r-jg9r-vq44

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

simple-crypto-js fixed: 2.3.0 
npm install simple-crypto-js@2.3.0
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 simple-crypto-js

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-5v7r-jg9r-vq44, inspect your project dependencies using npm:

npm ls simple-crypto-js

Analyze the terminal output to locate any version of Simple crypto js in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.0), your application is affected.

Note: The npm ls simple-crypto-js 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-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. In Simple crypto js, 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 `simple-crypto-js` prior to 2.3.0 use AES-CBC with PKCS#7 padding, which is vulnerable to padding oracle attacks. This may allow attackers to break the encryption and access sensitive data. ## Recommendation Upgrade to version 2.3.0 or later.
