CVE-2026-42203

A flaw was found in LiteLLM, an AI Gateway. An authenticated user could exploit this by sending a crafted prompt template to the POST /prompts/test endpoint. The endpoint rendered user-supplied prompt templates without proper sandboxing. This could lead to arbitrary code execution within the LiteLLM Proxy process, potentially exposing sensitive information such as API keys or database credentials, and allowing commands to be run on the host system.
