Advisory
Source description from Wordfence Intelligence, credited to SOPROBRO.
The WordPress Meta Data and Taxonomies Filter (MDTF) plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.3.3.4 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.
