Ultimate Bootstrap Elements for Elementor < 1.3.7 - Contributor+ Stored XSS

Description

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