SVG with embedded scripts can lead to cross-site scripting attacks in 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>
```
This vulnerability impacts website that publish HTML drafts and RFCs.
This has been fixed in version [3.12.4](https://github.com/ietf-tools/xml2rfc/releases/tag/v3.12.4).
If SVG source is self-contained within the XML, scraping script elements from SVG files.
