An improper authorization vulnerability exists in the main-latest version of BerriAI/litellm. When a user with the role internal_user_viewer logs into the application, they are provided with an overly privileged API key. This key can be used to access all the admin functionality of the application, including endpoints such as /users/list and /users/get_users. This vulnerability allows for privilege escalation within the application, enabling any account to become a PROXY ADMIN.
A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
