Moodle – Cross-site Scripting (XSS)


During the scan, Kayran managed to find an XSS vulnerability inside the Moodle platform.
Cross-site scripting (XSS) is a security vulnerability in web applications that is caused by not properly validating inputs from the user, which could allow an attacker to inject malicious JavaScript code.

Cross-site scripting (XSS) can allow an attacker to run JavaScript code on the site which means he can change and manipulate the content of the site as he pleases.
When chained with more vulnerabilities, this attack could be a lot more dangerous and even cause situations like accounts takeovers.


CVSS Version 3.x – 6.1 Medium


Update to the latest version released by Moodle.
