CVE-2023-3303Public exploitNetwork attack vector

Restricted photo disclosure via missing album visibility check

Published Jun 23, 2023 · Updated Nov 7, 2024

Improper access control in Admidio before 4.2.9 allows remote authenticated users to access restricted photo albums through e-card requests. The ecard_send.php handler loads an album selected by photo_uuid but fails to call TablePhotos::isVisible() before using its photos. A low-privileged account and recipient interaction with the resulting e-card are required, and the bounded consequence is disclosure of restricted album content.
