Description
The bSlider plugin for WordPress is vulnerable to Sensitive Information Exposure via the bsbPosts AJAX action in versions 2.0.17 up to, and including, 2.2.2. The handler trusts the ACF field names the browser sends and does not check that the slider block was configured to show them. This makes it possible for unauthenticated attackers to read the values of any ACF field assigned to a public post type on published posts, including fields that were never meant to be displayed. The attacker needs the nonce that the plugin prints on pages containing a post slider.
