Recommendation: Monitor — no exploitation signal at the moment.

The Custom Post Type UI plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'label' parameter during custom post type import in all versions up to, and including, 1.18.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses the Tools → Get Code page.
