CVE-2025-51482Public exploitNetwork attack vector

Remote code execution via unrestricted tool source

Published Jul 22, 2025 · Updated Jul 22, 2025

Code injection in letta-ai Letta 0.7.12 allows remote attackers to execute Python code and system commands through /v1/tools/run. The run_tool_from_source route passes attacker-supplied source and environment variables through the local sandbox to exec() without blocking dangerous modules or system functions. The endpoint is unauthenticated and network-exposed by default, and commands run with the Letta server process's permissions, including root when deployed that way.
