What the vulnerability does
The Set Bulk Post Categories plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1. This is due to missing nonce validation on the bulk category update functionality. This makes it possible for unauthenticated attackers to modify post categories in bulk via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Set Bulk Post Categories versions 1.1 and earlier are vulnerable to cross-site request forgery (CSRF). An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions such as modifying post categories without the admin's knowledge or consent. The vulnerability requires the victim to visit the attacker's page while authenticated to the WordPress site.
What an attacker can do
Trick a logged-in admin into modifying post categories without their knowledge via a malicious webpage.
Potential impact on your site
Post categories can be changed without admin authorization if an admin visits a malicious link while logged in.
Conditions required to exploit
Admin must be logged in and visit an attacker-controlled webpage; no special privileges or authentication by the attacker required.
