payload 3.90.0

Full technical detail▾

Overview

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.

Affected

payload >= 3.0.0, < 3.90.0
payload = 4.0.0

Remediation

Upgrade past the affected range:

payload 3.90.0

Package advisory (CVE-2026-105851)
