What the vulnerability does
The Meta-box GalleryMeta plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'mb_gallery' custom post type in all versions up to, and including, 3.0.1. This makes it possible for authenticated attackers, with Author-level access and above, to create and publish galleries.
Explanation of Vulnerability in Simple Terms
Meta-box GalleryMeta versions 3.0.1 and earlier lack proper authorization checks, allowing authenticated users to modify gallery data they should not have access to. An attacker with low-privilege account access can alter gallery content without proper permission validation. The vulnerability affects the integrity of gallery data but does not expose sensitive information or disrupt availability.
What an attacker can do
Modify gallery data and settings without proper authorization.
Potential impact on your site
Unauthorized users can alter gallery content, potentially defacing or corrupting image galleries.
Conditions required to exploit
Attacker must have a low-privilege user account on the site.
