Element Pack Addons for Elementor < 8.1.0 - Authenticated (Contributor+) DOM-Based Stored Cross-Site Scripting via data-caption Attribute

Description

The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data-caption’ attribute in all versions up to, and including, 8.0.0 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.
