BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.39, src/bentoml/internal/container/frontend/dockerfile/templates/basev2.j2 interpolates docker.baseimage raw with no escaping, newline filtering, or validation. A malicious...

GHSA-MCFX-4VC6-QGXV BentoML has Information Disclosure in `bentoml build` via symlink traversal in the build context

Summary BentoML's bentoml build packaging workflow follows attacker-controlled symlinks inside the build context and copies the referenced file contents into the generated Bento artifact. If a victim builds an untrusted repository or other attacker-supplied build context, the attacker can place a...

CVE-2026-33744

BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.37, the docker.systempackages field in bentofile.yaml accepts arbitrary strings that are interpolated directly into Dockerfile RUN commands without sanitization. Since...

CVE-2026-27905 BentoML has an Arbitrary File Write via Symlink Path Traversal in Tar Extraction

BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.36, the safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path,...

BentoML Vulnerable to Arbitrary File Write via Symlink Path Traversal in Tar Extraction

Arbitrary File Write via Symlink Path Traversal in Tar Extraction Summary The safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a...

BentoML path traversal vulnerability

BentoML is an open-source model service library developed by BentoML. It is used to build high-performance and scalable artificial intelligence applications using Python. Versions of BentoML prior to 1.4.34 contained a path traversal vulnerability. This vulnerability stemmed from the bentofile.ya...
