Vulnerability Description
The Schema & Structured Data for WP & AMP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'saswp_tiny_multiple_faq' shortcode in all versions up to, and including, 1.51 due to insufficient input sanitization and output escaping on user supplied attributes.
