Zipline before 4.6.2 contains a missing authorization vulnerability in POST /api/user/folders that allows authenticated users to reparent other users' files by supplying their file IDs. Attackers can harvest file IDs from public folders and create a folder seeded with them, disclosing victims' file URLs and removing those files from their folder views.
