Six months ago we discovered an Authentication Bypass Vulnerability in the Auth0 platform. After working with them, today, we can disclose the full details:

"With more than 2000 enterprise customers and managing 42 million logins every single day, Auth0 is one of the biggest Identity Platforms. In this post we will tell the story of how we, at Cinta Infinita, found an Authentication Bypass Vulnerability that affected any application using Auth0 (for username and password authentication) in the context of an independent non-profitable research.
We will demonstrate the flaw attacking the Auth0 Management Console (used as one exploitable example application).”
