CVE-2026-42208LiteLLM — SQL injection in the proxy key check

LiteLLM 1.81.16 through 1.83.6 pastes the caller's key straight into a SQL query while checking it, so an unauthenticated attacker can reach that query with a crafted header and read — possibly change — the proxy's database and the credentials it holds.

YOUR NEXT MOVE

Upgrade LiteLLM to 1.83.7 or later now; assume the key table was read and rotate every provider credential the proxy holds.
