## Overview

Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, a malformed multipart request body can cause multipart Content-Type processing to take an extremely long time, resulting in uncontrolled resource consumption. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
