Technical details

A reflected cross-site scripting (XSS) vulnerability exists in Moodle versions 3.1.x (up to 3.1.3) and 3.2.0 within the assignment submission component. The flaw stems from improper neutralization of user-supplied input before it is rendered on the page (CWE-79). An attacker can exploit this by tricking a user into visiting a specially crafted URL or interacting with malicious content on the submission page. If successful, the attacker can execute arbitrary JavaScript in the context of the victim's session, potentially leading to session hijacking or unauthorized data access. Moodle has released patches to address this issue.
