What the vulnerability does
The Category Dropdown List plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the `$_SERVER['PHP_SELF']` variable in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Category Dropdown List versions 1.0 and earlier contain a cross-site scripting (XSS) vulnerability. An attacker can inject malicious scripts into category dropdown fields that execute in other users' browsers when they view the affected page. The vulnerability requires user interaction—a victim must visit a page containing the malicious payload. Impact is limited to session hijacking or credential theft within the scope of the affected site.
