LibrePhotos before 1.0.0 contains a broken object level authorization vulnerability in the SetPhotosShared endpoint that allows authenticated users to grant themselves access to other users' private photos by bypassing ownership validation. Attackers can manipulate shared_to relations without proper owner checks to read arbitrary private photos belonging to other users.
