Magical Products Display <= 1.1.29 - Authenticated (Contributor+) Stored Cross-Site Scripting via MPD Pricing Table Widget

The Magical Products Display plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'mpdpr_title_tag' and 'mpdpr_subtitle_tag' parameters in the MPD Pricing Table widget in all versions up to, and including, 1.1.29 due to insufficient input sanitization and output escaping on user-supplied HTML tag names. 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.
