Meelo through 3.13.1 contains a missing authorization vulnerability that allows authenticated non-admin users to modify shared catalog data because RolesGuard does not require Admin on song, track and video write routes. Attackers can send PUT requests to /songs/:idOrSlug, /tracks/:idOrSlug or /videos/:idOrSlug, or POST to /songs/:idOrSlug/merge, to alter genres, reassign tracks and merge songs.
