BentoML < 1.4.34 Path Traversal

high Nessus Plugin ID 298466

Synopsis

The BentoML library installed on the remote host is affected by a path traversal vulnerability.

Description

The version of the BentoML library installed on the remote host is prior to 1.4.34. It is, therefore, affected by a path traversal vulnerability:

 - BentoML's bentofile.yaml configuration allows path traversal attacks through multiple file path fields (description, docker.setup_script, docker.dockerfile_template, conda.environment_yml). An attacker can craft a malicious bentofile that, when built by a victim, exfiltrates arbitrary files from the filesystem into the bento archive. This enables supply chain attacks where sensitive files (SSH keys, credentials, environment variables) are silently embedded in bentos and exposed when pushed to registries or deployed. (CVE-2026-24123)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to BentoML version 1.4.34 or later.
