CVE-2025-48921Network attack vector

Enrollment changes via insufficiently protected routes

Published Jun 26, 2025 · Updated Jun 26, 2025

CSRF in Drupal Open Social before 12.3.14 and 12.4.0 through 12.4.12 allows remote attackers to alter event enrollments. The default event-enrollment module accepts state-changing enrollment acceptance or rejection requests on routes without sufficient CSRF protection. Exploitation requires event enrollments to be enabled for an event and an authenticated user to be tricked into sending the forged request.
