CVE-2026-15035Public exploit

Local arbitrary command execution via shell-joined repository names

Published Jul 8, 2026 · Updated Jul 8, 2026

OS command injection in BentoML OpenLLM 0.6.30 allows local users to execute arbitrary commands through a malicious model repository. async_run_command joins an argument list containing an unsanitized model tag derived from repository directory names, then passes the string to create_subprocess_shell. Execution requires adding and running or serving an attacker-controlled repository; shell metacharacters in its model or version directory name run with the OpenLLM process privileges.
