Affected: Homebrew: xml2rfc

xml2rfc allows `script` elements in SVG sources. In HTML output having these script elements can lead to XSS attacks.

Sample XML snippet: ``` <artwork type="svg" src="data:image/svg+xml,%3Csvg viewBox='0 0 10 10' xmlns='http://www.w3.org/2000/svg'%3E%3Cscript%3E window.alert('Test Alert'); %3C/script%3E%3C/svg%3E"> </artwork> ```

### Impact This vulnerability impacts website that publish HTML drafts and RFCs.

### Patches This has been fixed in version [3.12.4](https://github.com/ietf-tools/xml2rfc/releases/tag/v3.12.4).

### Workarounds If SVG source is self-contained within the XML, scraping `script` elements from SVG files.
