## Description

The Addon Elements for Elementor (formerly Elementor Addon Elements) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post titles displayed by the Post List widget in all versions up to, and including, 1.14.5 due to insufficient output escaping. The widget printed post titles with the_title() directly inside link title attributes, so a crafted title can break out of the attribute. The widget only lists published posts. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses a page containing the widget.
