Royal Elementor Addons < 1.7.1050 - Contributor+ Stored XSS via REST API Meta Bypass

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the 'button_text' parameter 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.
