What the vulnerability does
The Popover Windows plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on multiple ajax actions (e.g., pop_submit, poptheme_submit) in all versions up to, and including, 1.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify the plugin's settings and content.
Explanation of Vulnerability in Simple Terms
Popover Windows versions 1.2 and earlier lack proper authorization checks, allowing authenticated users to modify content they should not have access to. An attacker with a low-privilege account can alter data through the application's API or interface. The vulnerability has low integrity impact and does not affect confidentiality or availability. Update to a version newer than 1.2.
What an attacker can do
Modify content or settings they lack permission to change.
Potential impact on your site
Unauthorized users could alter site content, settings, or data they should not access.
Conditions required to exploit
Attacker must have a valid low-privilege user account on the site.
