What the vulnerability does
The Vimeo SimpleGallery plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 0.2. This is due to missing authorization checks on the `vimeogallery_admin` function hooked to `admin_menu`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary plugin settings via the `action` parameter.
Explanation of Vulnerability in Simple Terms
Vimeo SimpleGallery versions 0.2 and earlier lack proper authorization checks, allowing authenticated users to modify gallery content they should not have access to. An attacker with low-level site access can alter or corrupt galleries belonging to other users or administrators. The vulnerability requires an existing user account but no special privileges.
What an attacker can do
Modify or delete galleries belonging to other users without permission.
Potential impact on your site
Galleries can be altered or deleted by unauthorized users, risking data loss and site integrity.
Conditions required to exploit
Attacker must have a low-privilege user account on the site.
