## Description

The Logo Carousel plugin for WordPress is vulnerable to Sensitive Information Exposure via the lc_template shortcode and the page builder template widgets in all versions up to, and including, 4.0.1. This is due to the saved template renderer outputting a published template's content without checking whether the template is password protected. This makes it possible for unauthenticated attackers to view the contents of password-protected saved templates wherever they are embedded, without entering the password. Authenticated attackers with Contributor-level access and above can also embed a protected template's ID in their own posts to view it.
