CVE-2024-3645 | Essential Addons for Elementor Pro <= 5.8.11 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title_html_tag'

The Essential Addons for Elementor Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Counter widget in all versions up to, and including, 5.8.11 due to insufficient input sanitization and output escaping on user supplied attributes such as 'title_html_tag'. 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.
