Description

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.
