## Description

The Xagio SEO & AEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' attribute of Link Manager tracking shortcodes in all versions up to, and including, 7.1.0.51 due to insufficient input sanitization and output escaping on user supplied shortcode attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that at least one Link Manager shortcode exists on the site.
