Description
The Happy Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Image Stack Group widget in all versions up to, and including, 3.10.7 due to insufficient input sanitization and output escaping on user supplied 'tooltip_position' attribute. 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.
