The Plus Addons for Elementor – Elementor Addons, Page Templates, Widgets, Mega Menu, WooCommerce < 5.5.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via Heading Title Widget

Description

The The Plus Addons for Elementor Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'size' attribute of the Heading Title widget in all versions up to, and including, 5.5.4 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
