CVE-2026-55212 – Pimcore: Insufficient Permission Check on Class Definition Creation Endpoint Allows Privilege Escalation

CVE ID :CVE-2026-55212

Published : July 9, 2026, 9:16 p.m. | 32 minutes ago

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.

Severity: 7.1 | HIGH
