BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to version 1.4.34, 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. Version 1.4.34 contains a patch for the issue.
AnalysisAI
BentoML versions prior to 1.4.34 allow path traversal attacks through improperly validated file path fields in bentofile.yaml configurations, enabling attackers to embed arbitrary files from the victim's system into bento archives during the build process. This vulnerability can be exploited to exfiltrate sensitive data such as credentials, SSH keys, and environment variables into supply chain artifacts that may be pushed to registries or deployed in production environments. …
