### KaTeX \htmlData does not validate attribute names
[CVE-2025-23207](https://nvd.nist.gov/vuln/detail/CVE-2025-23207) / [GHSA-cg87-wmx4-v546](GHSA-cg87-wmx4-v546)

<details>
<summary>More information</summary>

#### Details
##### Impact
KaTeX users who render untrusted mathematical expressions with `renderToString` could encounter malicious input using `\htmlData` that runs arbitrary JavaScript, or generate invalid HTML.

##### Patches
Upgrade to KaTeX v0.16.21 to remove this vulnerability.

##### Workarounds
- Avoid use of or turn off the `trust` option, or set it to forbid `\htmlData` commands.
- Forbid inputs containing the substring `"\\htmlData"`.
- Sanitize HTML output from KaTeX.

##### Details
`\htmlData` did not validate its attribute name argument, allowing it to generate invalid or malicious HTML that runs scripts.
