Improper Check for Unusual or Exceptional Conditions

CVE-2022-31093

Severity High
Score 7.5/10

Summary

Improper Handling of `callbackUrl` parameter in next-auth prior to 3.29.5, and 4.x prior to 4.5.0. An attacker can send a request to an app using NextAuth.js with an invalid callbackUrl query parameter, which internally we convert to a URL object. The URL instantiation would fail due to a malformed URL being passed into the constructor, causing it to throw an unhandled error which led to our API route handler timing out and logging in to fail.
