CVE-2026-57943
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.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
