Overview

A Cross-site Request Forgery (CSRF) vulnerability was discovered in Moodle's Brickfield tool (CVE-2025-3638). The analysis request action in the Brickfield tool failed to include the necessary security token, exposing the system to CSRF attacks. This vulnerability affects Moodle versions 4.5 to 4.5.3, 4.4 to 4.4.7, 4.3 to 4.3.11, 4.1 to 4.1.17, and earlier unsupported versions (NVD, Red Hat CVE).

This indicates that the vulnerability can be exploited remotely, requires low attack complexity, needs no privileges, but does require user interaction (NVD).

Impact

If successfully exploited, this CSRF vulnerability could allow attackers to perform unauthorized actions in the context of authenticated users of the Moodle platform, potentially leading to high impacts on confidentiality, integrity, and availability of the system (NVD).

Mitigation and workarounds
