The Xagio SEO plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 7.1.0.5 via the backup functionality due to weak filename structure and lack of protection in the directory. This makes it possible for unauthenticated attackers to extract sensitive data from backups which can include the entire database and site's files.

The Xagio SEO – AI Powered SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘HTTP_REFERER’ parameter in all versions up to, and including, 7.1.0.16 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability was partially patched in version 7.1.0.0.
