How to fix?

Upgrade payload to version 3.90.0, 4.0.0-canary.34 or higher.

Overview

payload is a Node, React and MongoDB Headless CMS and Application Framework

Affected versions of this package are vulnerable to Incorrect Authorization via the collection duplication endpoint (/:id/duplicate), where the disableDuplicate collection setting was not enforced at the operation level. An unauthenticated remote attacker can send a POST request to the duplicate endpoint of an auth-enabled collection, bypassing the intended access control restriction and writing duplicate documents to collections that should prohibit duplication. The disableDuplicate flag was only used to suppress the endpoint registration in some code paths, but the underlying createOperation did not independently verify the flag, allowing the restriction to be circumvented.

Note: This is only exploitable against collections where disableDuplicate is set (including auth collections, where it is enabled by default), because those are the collections the access control was intended to protect.
