Published:August 30, 2026
Updated:September 24, 2026
Admidio versions before 5.0.12 contain a broken access control vulnerability in profile_function.php that allows authenticated low-privilege users to read another user's future role memberships. Attackers can bypass profile-level authorization by directly calling the reload_future_memberships endpoint with a victim's user UUID to disclose sensitive membership information.
