What the vulnerability does
01Description
The 评论小秘书 plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the `$_SERVER['PHP_SELF']` variable in all versions up to, and including, 1.3.2. This is due to insufficient input sanitization and output escaping on the `$_SERVER['PHP_SELF']` variable in the plugin's settings page. 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.

02Summary
The 评论小秘书 product through version 1.3.2 contains a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts. An attacker can craft a malicious link or page that, when visited by a user, executes arbitrary JavaScript in the victim's browser. This can lead to session hijacking, credential theft, or defacement. The vulnerability requires user interaction and affects the scope beyond the vulnerable component.
