## Affected

- magazine3 Schema & Structured Data for WP & AMP: through 1.51

## 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. 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.
