CVE-2026-32932Network attack vector

Administrator redirection and session disclosure via unvalidated page

Published Apr 10, 2026 · Updated Apr 10, 2026

Open redirect in Chamilo LMS before 1.11.38 and 2.0.0-alpha.1 through 2.0.0-RC.2 allows remote attackers to redirect administrators. The session course edit handler passes the user-controlled page parameter, after XSS filtering but without same-origin validation, into the Location header and appends id_session. Exploitation requires an authenticated administrator to save coach assignment changes, after which the browser visits the external URL and discloses the session identifier.
