CVE-2026-110776
Description
The MDTF – Meta Data and Taxonomies Filter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'vars' parameter in all versions up to, and including, 1.4.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires that a published page or post on the target site contains the [meta_data_filter_results] shortcode, which is the primary output feature of the plugin.
