Summary
The MDTF (Meta Data and Taxonomies Filter) plugin for WordPress is affected in all versions up to and including 1.4.1. Insufficient input sanitization and output escaping of the 'vars' parameter enable stored cross-site scripting (CWE-79). An unauthenticated attacker can inject scripts that run when a user accesses an injected page, provided a published page or post contains the [meta_data_filter_results] shortcode.

Description from the CNA
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.
