How to Fix GHSA-vjvw-wcmw-pr26

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

parsel fixed: Latest secure release 
npm install parsel@Latest secure release
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 parsel

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-vjvw-wcmw-pr26, inspect your project dependencies using npm:

npm ls parsel

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

Note: The npm ls parsel 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-331: Insufficient Entropy, where the product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others. In Parsel, 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

All versions of `parsel` use an insecure key derivation function. The package runs keys of arbitrary lengths through one round of SHA256 hashing for key stretching. This allows for the use of keys of insufficient entropy with inappropriate key stretching. ## Recommendation The package is deprecated and will not be updated. Consider using an alternative package.
