Magic the Gathering Card Tooltips <= 3.4.0 is vulnerable to Cross Site Scripting (XSS) vulnerability

The Magic the Gathering Card Tooltips plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.4.0 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 in pages that will execute whenever a user accesses an injected page.
