CVE-2024-3924Network attack vector

Runner code execution via unquoted branch name

Published May 30, 2024 · Updated Aug 1, 2024

Code injection in Hugging Face Text Generation Inference before 2.0.0 allows remote authenticated users to execute code on a GitHub Actions runner. The autodocs.yml install step interpolates github.head_ref directly into an unquoted shell command, allowing branch-name metacharacters to alter the command. Exploitation requires a fork, a malicious branch name, a pull request to the base repository, and maintainer-triggered workflow execution; impact is confined to the runner context.
