The Plus Addons for Elementor < 5.5.3 - Contributor+ Stored XSS

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the ‘button_custom_attributes’ parameter due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
