How to Fix CVE-2023-46943

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

@evershop/evershop fixed: 1.0.0-rc.9 
npm install @evershop/evershop@1.0.0-rc.9
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 @evershop/evershop

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-46943, inspect your project dependencies using npm:

npm ls @evershop/evershop

Analyze the terminal output to locate any version of @evershop/evershop in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.0-rc.9), your application is affected.

Note: The npm ls @evershop/evershop 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In @evershop/evershop, 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

An issue was discovered in NPM's package @evershop/evershop before version 1.0.0-rc.9. The HMAC secret used for generating tokens is hardcoded as "secret". A weak HMAC secret poses a risk because attackers can use the predictable secret to create valid JSON Web Tokens (JWTs), allowing them access to important information and actions within the application.
