Overview

moodle/moodle is a learning platform.

Affected versions of this package are vulnerable to Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') due to insufficient sanitizing of TeX content when the TeX notation filter is enabled. An attacker can inject malicious scripts by crafting specific TeX content.

Note:

This is only exploitable if the TeX notation filter is enabled.
