Input validation vulnerability in Royal Elementor Addons and Templates 1.3.980

The Royal Elementor Addons and Templates plugin for WordPress has a security issue that can allow unauthorized users to inject harmful code into pages. This can happen when using the Magazine Grid/Slider widget and affects all versions up to 1.3.980. This vulnerability is caused by a lack of proper filtering and protection of user input, making it possible for attackers with contributor-level access or higher to insert malicious code that will run when a user views the affected page.
