Description

The aThemes Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'title_tag' Widget Setting in all versions up to, and including, 1.1.8 due to insufficient input sanitization and output escaping. 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. This affects the Posts Timeline widget as well as the Posts Carousel widget across its default, Banner, and Modern skins, all of which omit the whitelist validation that is correctly applied in the Posts List widget.
