What is CVE-2026-72540?

An insecure direct object reference vulnerability in PhotoPrism exposes users to potential privacy risks by allowing unauthorized access to original-resolution album cover photos. Users with a valid preview token are able to retrieve the cover images of any album, as the AlbumCover handler lacks necessary checks to verify user authorization. This allows attackers to enumerate and download album cover images belonging to other users, leading to exposure of sensitive information.
