Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

LiteLLM versions before 1.83.0 are affected by a chain of issues that lets an authenticated user take over another account. Password hashes are unsalted SHA-256 and are returned by several API endpoints to any authenticated user, and the login endpoint accepts the raw hash as a password, so an attacker can log in as another user and escalate privileges. Upgrade to LiteLLM 1.83.0, which uses scrypt hashing, removes hashes from API responses, and migrates existing hashes on next login.
