Description
The WP SEO Structured Data Schema plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘Price Range’ parameter in all versions up to, and including, 2.7.11 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts that will execute whenever an administrator accesses the plugin settings page.
