What it is

From the CVE record

Kiteworks Core contains a business logic flaw in a Kiteworks file-request feature allowed an authenticated user to send a request that appeared to originate from another user, because the server did not verify that the requester was authorized to act as the specified account. This could be used to solicit files or information from a recipient under a trusted identity; exploitation requires the feature to be enabled for the attacker's profile and the targeted recipient to act on the request.
