How to Fix CVE-2025-67490

To remediate this vulnerability, upgrade all affected @auth0/nextjs auth0 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/nextjs-auth0 fixed: 4.11.2 
npm install @auth0/nextjs-auth0@4.11.2
@auth0/nextjs-auth0 fixed: 4.12.1 
npm install @auth0/nextjs-auth0@4.12.1
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/nextjs-auth0

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-67490, inspect your project dependencies using npm:

npm ls @auth0/nextjs-auth0

Analyze the terminal output to locate any version of @auth0/nextjs auth0 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.11.2), your application is affected.

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

Technical Details
