How to Fix CVE-2018-7307

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: 9.3.0 
npm install auth0-js@9.3.0
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 auth0-js

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2018-7307, 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 9.3.0), 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.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Auth0 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

The Auth0.js library has a vulnerability affecting versions below 9.3 that allows an attacker to bypass the CSRF check from the state parameter if it's missing from the authorization response, leaving the client vulnerable to CSRF attacks.
