## Description

The CCI Posts Carousel All In One plugin for WordPress is vulnerable to Sensitive Information Exposure via the public /wp-posts-carousel/v1/carousel/{id} REST endpoint in all versions up to, and including, 2.1.0, due to the endpoint returning the complete stored carousel configuration, including the labels of manually selected posts. This makes it possible for unauthenticated attackers to read the titles of private or since-unpublished posts that an administrator selected into a published carousel.
