SCA: security update for bentoml (GHSA-mcfx-4vc6-qgxv)

medium Tenable Cloud Security Plugin ID 441485

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - BentoML is a Python library for building online serving systems optimized for AI apps and model inference.
 In versions 1.4.38 and prior, the 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 symlink
 such as loot.txt -> /tmp/outside-marker.txt or a link to a more sensitive local file. When bentoml build
 runs, BentoML dereferences the symlink and packages the target file contents into the Bento. The leaked
 file can then propagate further through export, push, or containerization workflows. An attacker can
 exfiltrate local files from the build host into the Bento artifact, exposing secrets such as cloud
 credentials, SSH keys, API tokens, environment files, or other sensitive local configurations. Because
 Bento artifacts are commonly exported, uploaded, stored, or containerized after build, the leaked file
 contents can spread beyond the original build machine. This issue has been fixed in version 1.4.39.
 (CVE-2026-40610)

Solution

Update the bentoml library and its related packages to version 1.4.39 or later.
