Original NVD 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.
