Gokapi is a self-hosted file sharing server with automatic expiration and encryption support. Prior to 2.2.4, An insufficient authorization check in the file replace API allows a user with only list visibility permission (UserPermListOtherUploads) to delete another user's file by abusing the deleteNewFile flag, bypassing the requirement for UserPermDeleteOtherUploads. This vulnerability is fixed in 2.2.4.
