AI-suggested
Users should avoid using affected versions (<= 0.3.1) of the wenxian tool in environments where untrusted input can reach GitHub Actions workflows. Consider disabling or restricting GitHub Actions workflows that process untrusted issue comments until a fix is released. Monitor the vendor's repository and advisories for updates and patches.
Description
wenxian is a tool to generate BIBTEX files from given identifiers (DOI, PMID, arXiv ID, or paper title). In versions 0.3.1 and prior, a GitHub Actions workflow uses untrusted user input from issue_comment.body directly inside a shell command, allowing potential command injection and arbitrary code execution on the runner. At time of publication, there are no publicly available patches.
