CVE-2026-53634 · Severity: medium · CVSS 4.3 · Published 2026-06-10

A vulnerability in the Sharp content management framework allows authenticated users to create or view data they are not authorized to access. By using the 'Quick Creation Command' feature, a user who should only have limited access can bypass security checks to submit new records or view creation forms. This could lead to unauthorized data entry and minor integrity issues within the application.

Technical details

A missing authorization check (CWE-862) exists in the 'create' and 'store' endpoints of the Quick Creation Command feature in code16/sharp. Authenticated users who lack explicit 'create' permissions for a specific entity can bypass the authorization layer if a Quick Creation Command handler is configured for that entity. This allows the attacker to retrieve the creation form or successfully submit new records. The vulnerability is reachable over the network by any authenticated user. A fix is available in version 9.22.3.
