Private photo disclosure via unchecked sharing relation
Published Jun 29, 2026 · Updated Jun 29, 2026
Broken object-level authorization in LibrePhotos before 1.0.0 allows remote authenticated users to read other users' private photos. SetPhotosShared resolves request-supplied image hashes without filtering Photo objects by owner, then writes an attacker-chosen target user into shared_to. Exploitation requires a valid account and a victim photo hash; it exposes originals and thumbnails and permits removal of legitimate shares.
