## Description

The User Profile Builder plugin for WordPress is vulnerable to Sensitive Information Exposure via auto-generated post excerpts in all versions up to, and including, 4.0.6 due to restricted Gutenberg content restriction blocks and restricted Elementor elements not being stripped when excerpts are generated. This makes it possible for unauthenticated attackers to read content that was restricted at the block or element level through excerpts shown in archives, feeds, search results and the REST API.
