Description · from the CVE record

Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, an attacker can submit a request to a specific update endpoint that modifies collection documents without enforcing collection or field-level access control when orderable is enabled on a collection or join field. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
