Payload: Field access control bypass on auth collections
CVE-2026-105851
Payload is a free and open source headless content management system. In versions from 3.0.0 before 3.90.0 and canary versions before 4.0.0-canary.34, the duplicate operation copies values from a source document even when a field is hidden or its access.read or access.create rule rejects that value for the caller. The disableDuplicate setting does not prevent this access-control bypass. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.
