CVE-2026-47101 LiteLLM < 1.83.14 Privilege Escalation via API Key Generation

What is CVE-2026-47101?

CVE-2026-47101 is a high-severity vulnerability in BerriAI litellm, published on 21 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

LiteLLM prior to 1.83.14 allows an authenticated internal_user to create API keys with access to routes that their role does not permit. When generating a key, the allowed_routes 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 internal_user to proxy_admin.
