Description
### Impact CommonMark is configured with `html_input => 'escape'`, which blocks raw HTML injection. However, javascript: URIs in Markdown hyperlinks are not sanitized. A user with `assets.edit` permission can inject a malicious link into any markdown-textarea custom field. Any user who opens the asset detail page and clicks the link executes arbitrary JavaScript in their browser session.
