User Access Control Bypass in Payload CMS Versions Prior to 1.7.0

CVE-2023-30843 · MEDIUM Severity

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

Payload is a free and open source headless content management system. In versions prior to 1.7.0, if a user has access to documents that contain hidden fields or fields they do not have access to, the user could reverse-engineer those values via brute force. Version 1.7.0 contains a patch. As a workaround, write a `beforeOperation` hook to remove `where` queries that attempt to access hidden field data.
