LiteLLM prior to 1.83.14 allows an authenticated internaluser to create API keys with access to routes that their role does not permit. When generating a key, the allowedroutes field is stored without verifying that the specified routes fall within the user's own permissions. A key created with access to admin-only routes can then be used to reach those routes successfully, bypassing the role-based access controls that would otherwise block the request, enabling full privilege escalation from internaluser to proxyadmin.
