What is CVE-2018-6873?

The Auth0 authentication service prior to October 15, 2017, contains a vulnerability that allows attackers to escalate privileges due to the lack of validation for the JSON Web Token (JWT) audience. This oversight means that unauthorized users could gain elevated access and perform actions that would normally be restricted, putting sensitive user data at risk. It is crucial for users of Auth0 to review their implementation and ensure secure token management to mitigate this risk.
