What the vulnerability does
The Lesson Plan Book 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 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
Lesson Plan Book versions 1.3 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the application. 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 of the lesson plan interface.
What an attacker can do
Inject and execute malicious JavaScript in a user's browser to steal session data or credentials.
Potential impact on your site
Users viewing lesson plans could have their sessions compromised or personal data stolen if they click attacker-controlled links.
Conditions required to exploit
Attacker must trick a user into clicking a malicious link or visiting a crafted page (user interaction required).
