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.

    ## Impact An attacker can submit a request to a specific endpoint that permits collection documents to be updated regardless of access control and field level access control. **You are affected if:** - You are configuring `orderable: true` with any collection or join field. ## Patches In the patched version access control is properly enforced. Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.
