How to Fix CVE-2024-43370

To remediate this vulnerability, upgrade all affected Gettext.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.

gettext.js fixed: 2.0.3 
npm install gettext.js@2.0.3
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 gettext.js

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-43370, inspect your project dependencies using npm:

npm ls gettext.js
