What it is

TheHive through 4.1.24 contains a broken object-level authorization vulnerability in the attachment download endpoints that allows any authenticated user to access attachments belonging to other organizations by supplying a content-hash identifier. Attackers can exploit the missing organization-scoped authorization check in AttachmentSrv.visible, which is implemented as a pass-through traversal, to download arbitrary attachments.
