CVE-2026-39397: CWE-862: Missing Authorization in delmaredigital payload-puck
A critical authorization bypass vulnerability exists in delmaredigital's payload-puck plugin for PayloadCMS versions prior to 0. 6. 23. The plugin's API endpoints under /api/puck/* improperly override access controls, ignoring collection-level access rules and allowing unauthenticated users to perform CRUD operations. This flaw is identified as CWE-862 (Missing Authorization) and has a CVSS score of 9. 4. The vulnerability is fixed in version 0. 6. 23. No official patch advisory or exploit reports are currently available.
AI Analysis
Technical Summary
The delmaredigital payload-puck plugin for PayloadCMS versions before 0.6.23 registers CRUD API endpoints that call Payload's local API with overrideAccess set to true by default. This configuration bypasses all collection-level access controls, effectively ignoring any access options passed to createPuckPlugin() and any access rules defined on Puck-registered collections. As a result, unauthorized users can access and manipulate data via these endpoints. The vulnerability is tracked as CVE-2026-39397 and classified under CWE-862 (Missing Authorization). It is resolved in version 0.6.23.
Potential Impact
Unauthorized users can perform create, read, update, and delete operations on collections managed by the payload-puck plugin without any access restrictions. This leads to a complete compromise of confidentiality and integrity of the affected data, with a low impact on availability. The CVSS 3.1 score of 9.4 reflects the critical nature of this vulnerability due to network attack vector, no required privileges or user interaction, and high impact on confidentiality and integrity.
Mitigation Recommendations
Upgrade the payload-puck plugin to version 0.6.23 or later, where this authorization bypass vulnerability is fixed. Since no official vendor advisory or patch link is provided, users should verify the plugin version and apply the update promptly. Until updated, restrict access to the affected API endpoints if possible to reduce exposure.
