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

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 49: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 49% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes @delmaredigital/payload-puck (npm) < 0.6.23, fixed in 0.6.23 . Check your lockfile, including transitive dependencies.

## What it is

@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.

## Affected packages

- npm `@delmaredigital/payload-puck` < 0.6.23 → fixed: 0.6.23

## Affected products (CVE record)

- delmaredigital payload-puck: < 0.6.23

## Severity

- GitHub_M CVSS 3.1: 9.4 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L`
- GitHub CVSS 3.1: 9.4 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.61% probability of exploitation activity in the next 30 days; percentile 49.
