CVE-2026-55212 Details
Description
Pimcore is an Open Source Data & Experience Management Platform. Prior to 2025.4.6 and 2026.1.6, the Studio API class definition creation endpoint POST /pimcore-studio/api/class/definition/configuration-view/detail/create is guarded by the objects permission instead of the classes permission, allowing a standard editor-level user to create class definitions without admin privileges. Class definition creation generates new database tables and PHP class files on the server, and missing API-layer UID format validation allows malformed UIDs to reach model-layer validation and return internal exceptions. This issue is fixed in versions 2025.4.6 and 2026.1.6.
A vulnerability exists in the Pimcore Studio API class definition creation endpoint, specifically in versions prior to 2025.4.6 and 2026.1.6. The endpoint is protected by the objects permission, allowing standard editor-level users to create class definitions without admin privileges. This unauthorized access can lead to privilege escalation, as class definition creation is a structural admin task that generates new database tables and PHP class files on the server. Additionally, the API layer lacks proper validation for the UID format, allowing malformed UIDs to cause internal exceptions.
Users can upgrade to Pimcore versions 2025.4.6 or 2026.1.6, where this vulnerability has been patched.
