What the vulnerability does
The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘id’ parameter in all versions up to, and including, 4.2.6.6 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
LearnPress versions up to 4.2.6.6 contain a stored cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. These scripts execute in the browsers of other site visitors, potentially compromising their accounts or stealing sensitive data. The vulnerability affects the plugin's core functionality and impacts all site users.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they view affected pages.
Potential impact on your site
