    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) in the Markdown/RichText preview rendering process.

This is only exploitable if the attacker can place malicious content into the repository or content source loaded by the CMS.

    How to fix Cross-site Scripting (XSS)?
