What is CVE-2026-47101?

A vulnerability in LiteLLM prior to version 1.83.14 allows an authenticated internal user to generate API keys with access to restricted routes. The vulnerability allows the 'allowed_routes' field to be set without proper validation against the user's role permissions. As a result, keys can be created that grant access to admin-only routes, effectively bypassing role-based access controls. This enables attackers to escalate their privileges from an internal user to that of a proxy admin, potentially allowing unauthorized operations within the system.
