CVE-2026-112264 · BentoML through 1.4.39 Dockerfile Instruction Injection via docker.env Keys
This page contains facts from public vulnerability sources. Check the original advisory before updating.
BentoML through 1.4.39 contains a Dockerfile instruction injection vulnerability that allows attackers to add arbitrary build instructions by embedding newlines in docker.env mapping keys rendered by the legacy base.j2 template. Attackers can supply a crafted bentofile.yaml or imported bento archive so that bentoml containerize executes injected RUN instructions during docker build, accessing build secrets and poisoning images.
