EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (14th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
