CVE-2026-33744
March 27, 2026
BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.37, 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". Version 1.4.37 fixes the issue.
