## Overview

Payload is a free and open source headless content management system. In versions after 3.0.0 and before 3.90.0, authenticated external URL-based upload retrieval can forward authentication data to a redirected destination that was not verified as trusted, potentially exposing a valid session to an unintended recipient. This issue is fixed in version 3.90.0.
