CVE-2026-47101: Incorrect Authorization in BerriAI litellm
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.
AI Analysis
Technical Summary
CVE-2026-47101 is an incorrect authorization vulnerability in BerriAI's LiteLLM product before version 1.83.14. Authenticated users with the internal_user role can create API keys that include access to routes not permitted by their role because the system does not validate the allowed_routes field against the user's actual permissions. Consequently, these keys can be used to bypass role-based access controls and gain proxy_admin privileges, resulting in full privilege escalation. The vulnerability is tracked under CWE-639 (Authorization Bypass Through User-Controlled Key).
Potential Impact
An attacker with internal_user credentials can escalate privileges to proxy_admin by generating API keys with unauthorized access to admin-only routes. This bypasses intended role-based access controls, potentially allowing full administrative control over the affected LiteLLM instance.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch is currently documented. Until a patch is available, restrict internal_user role permissions and monitor API key creation processes closely to detect anomalous key generation.
