## Description

The Theme Builder For Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'text' setting of the Read More Button, Post Author, Post Date, Post Categories, Post Tags and Post Comments Elementor widgets in all versions up to, and including, 1.2.5, due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above who can edit posts with Elementor, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
