litellm: litellm: unauthenticated arbitrary file read leading to master key leakage and remote code execution

Published n/a CVSS 3.1 · 9.8 Critical EPSS n/a KEV · Not listed
Description
A critical vulnerability was discovered in LiteLLM Enterprise proxy where an unauthenticated remote attacker can trigger an arbitrary file read on any LLM route. This flaw allows an attacker to leak the proxy's master key (LITELLM_MASTER_KEY) and third-party model provider API credentials. With administrative proxy access obtained via the leaked master key, attackers can, in certain configurations, achieve remote code execution as root.
