How to Fix CVE-2017-17068

To remediate this vulnerability, upgrade all affected Auth0 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.

auth0-js fixed: 8.12.0 
npm install auth0-js@8.12.0
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 auth0-js

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2017-17068, inspect your project dependencies using npm:

npm ls auth0-js

Analyze the terminal output to locate any version of Auth0 js in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.12.0), your application is affected.

Note: The npm ls auth0-js command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
