## Overview

Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.88.0 and canary versions before 4.0.0-canary.27, an unauthenticated user can submit prototype-sensitive field paths when @payloadcms/plugin-import-export is enabled, causing unintended application behavior that can lead to remote code execution. This issue is fixed in versions 3.88.0 and 4.0.0-canary.27.
