# CVE-2026-39397: @delmaredigital/payload-puc is missing authorization on /api/puck/\* CRUD endpoints allows unauthenticated access to Puck-registered collections

- Also known as: GHSA-65W6-PF7X-5G85
- Severity: CVSS 9.4 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 0.6.23
- Published: 2026-04-07 · Updated: 2026-04-07

## Affected

- delmaredigital payload-puck: fixed in 0.6.23
- @delmaredigital/payload-puck (npm): fixed in 0.6.23

## Description

@delmaredigital/payload-puck is a PayloadCMS plugin for integrating Puck visual page builder. Prior to 0.6.23, all /api/puck/* CRUD endpoint handlers registered by createPuckPlugin() called Payload's local API with the default overrideAccess: true, bypassing all collection-level access control. The access option passed to createPuckPlugin() and any access rules defined on Puck-registered collections were silently ignored on these endpoints. This vulnerability is fixed in 0.6.23.
