📄 Description (English)

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'skin' attribute of the learn_press_courses shortcode in all versions up to and including 4.3.3. This is due to insufficient input sanitization and output escaping on the 'skin' shortcode attribute. The attribute value is used directly in an sprintf() call that generates HTML (class attribute and data-layout attribute) without any esc_attr() escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

🤖 AI Executive Summary

LearnPress WordPress LMS Plugin versions up to 4.3.3 contain a Stored XSS vulnerability in the learn_press_courses shortcode's 'skin' attribute due to insufficient input sanitization. Authenticated contributors can inject malicious scripts that execute for all users viewing affected pages.

📄 Description (Arabic)
