Hi,

The following vulnerability was published for node-katex.

CVE-2025-23207[0]:
| KaTeX is a fast, easy-to-use JavaScript library for TeX math
| rendering on the web. KaTeX users who render untrusted mathematical
| expressions with `renderToString` could encounter malicious input
| using `\htmlData` that runs arbitrary JavaScript, or generate
| invalid HTML. Users are advised to upgrade to KaTeX v0.16.21 to
| remove this vulnerability. Users unable to upgrade should avoid use
| of or turn off the `trust` option, or set it to forbid `\htmlData`
| commands, forbid inputs containing the substring `"\\htmlData"` and
| sanitize HTML output from KaTeX.
