This module enables you to analyze the content that you're authoring for a website. It shows you a preview of what a search result might look like.
The module doesn't sufficiently escape the metadata from content while rendering the preview, opening up the possibility of a XSS attack.
This vulnerability is mitigated by the fact that an attacker must be able to author content that is analyzed by the Real-Time SEO module.
