CVE-2024-38276Network attack vector

Cross-site request forgery via ignored token failures

Published Jun 18, 2024 · Updated Mar 26, 2025

CSRF in Moodle LMS 4.1.10 and earlier, 4.2 through 4.2.7, 4.3 through 4.3.4, and 4.4 allows remote attackers to perform user actions. Affected handlers called confirm_sesskey() but ignored its false return; the patches replace those calls with require_sesskey(), which stops invalid requests. A victim must be signed in and induced to submit a crafted request, and resulting actions run with that victim's privileges and depend on the affected endpoint.
