CVE-2026-47101
LiteLLM < 1.83.14 Privilege Escalation via API Key Generation
CVSS Score
8.8
EPSS Score
0.1%
EPSS Percentile
16th
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.
