📄 LiteLLM 1.83.0 Insecure Direct Object Reference

LiteLLM exposes a /config/update API endpoint that allows administrators to make configuration changes to the instance. Due to a missing authorization check, low-privileged users can access this endpoint without restriction. An attacker with a low-privileged account can exploit this to exfiltrate...

CVE-2026-42208

A flaw was found in LiteLLM. A database query used for proxy API key checks incorrectly incorporated caller-supplied key values directly into the query. This vulnerability allows an unauthenticated attacker to send a specially crafted Authorization header to any Large Language Model LLM API route...
