CVE-2026-40610 is a medium-severity flaw (CVSS 5.5) affecting bentoml. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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/outs
