CVE-2024-13340: Pluginus Meta Data And Taxonomies Filter

Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The MDTF – Meta Data and Taxonomies Filter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'mdf_results_by_ajax' shortcode in all versions up to, and including, 1.3.3.6 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

Affected products

• Pluginus Meta Data And Taxonomies Filter: before 1.3.3.7 (fixed in 1.3.3.7)
