## Affected

- jinghaihan turnpress: through 0.4.2

## Description

Turnpress through 0.4.2 contains an OS command injection vulnerability that allows attackers to execute shell commands by supplying .docx files with crafted names. The convertDocxToHtml function in src/converter.ts invokes pandoc through execa with shell:true, so shell metacharacters in the --docx path run with the victim's privileges during convert or create.
