CVE-2026-40217: LiteLLM through 2026-04-08 allows remote attackers to execute arbitrary code via bytecode rewriting at the /guardrails/t

LiteLLM (a library for working with multiple AI models) versions through April 8, 2026 contain a vulnerability that allows remote attackers to execute arbitrary code (run commands they shouldn't be able to run) through bytecode rewriting (modifying compiled code) at a specific web endpoint called /guardrails/test_custom_code. This is a serious security flaw because attackers on the internet could potentially take control of systems running vulnerable versions.
