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 product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
