CVE-2026-33744: BentoML has Dockerfile Command Injection via system_packages in bentofile.yaml

March 26, 2026 (updated June 8, 2026)

The docker.system_packages field in bentofile.yaml accepts arbitrary strings that are interpolated directly into Dockerfile RUN commands without sanitization. Since system_packages is semantically a list of OS package names (data), users do not expect values to be interpreted as shell commands. A malicious bentofile.yaml achieves arbitrary command execution during bentoml containerize / docker build.
