CVE-2026-102588
The XML grade import feature lacks proper Cross-Site Request Forgery (CSRF) token validation.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
Description
A flaw was found in Moodle. The XML grade import feature lacks proper Cross-Site Request Forgery (CSRF) token validation. By tricking an authenticated user with grade management permissions into visiting a malicious webpage, an attacker can trigger unauthorized requests on the victim's behalf. This flaw allows a remote attacker to set or overwrite student grades without authorization.
