CVE-2026-37004Network attack vector

Unauthenticated command execution via unsandboxed template rendering

Published Aug 27, 2026 · Updated Aug 27, 2026

Server-side template injection in BerriAI LiteLLM 1.82.4 and earlier allows remote attackers to execute OS commands via /prompts/test. The endpoint passes attacker-controlled dotprompt_content to an unsandboxed jinja2.Environment, which interprets template expressions as executable directives. No credentials or user interaction are required; successful requests run commands with the LiteLLM process's host privileges.
