What it is

The Essential Addons for Elementor – Popular Elementor Templates & Widgets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Event Calendar widget in all versions up to, and including, 6.6.2 due to insufficient input sanitization and output escaping on event titles sourced from The Events Calendar. 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 an injected page.
