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.

Affected: Packagist: pimcore/studio-backend-bundle

### Summary The Studio API class definition creation endpoint in `pimcore/studio-backend-bundle` is guarded by the `objects` permission instead of the `classes` permission, allowing any standard editor-level user to create class definitions without admin privileges. Class definition creation is a structural admin operation that generates new database tables and PHP class files on the server. Additionally, the API layer performs no format validation on the `uid` field before passing it to the model layer, relying solely on model-level validation that exists downstream in `ClassDefinition::saveClassInternal()`.

### Details

### Issue 1 — Incorrect permission guard on CreateController

`studio-backend-bundle/src/Class/Controller/DefinitionConfiguration/CreateController.php`:

```php #[IsGranted(UserPermissions::DATA_OBJECTS->value)] ```

The endpoint `POST /pimcore-studio/api/class/definition/configuration-view/detail/create` is protected by `DATA_OBJECTS` (the `objects` permission), which is a standard editor-level permission granted to content editors for creating and editing data objects. Class definition creation is a structural admin operation equivalent to schema modification, it creates new database tables and generates PHP class files on the server. This operation should require the `classes` permission, which is the permission Pimcore enforces for class definition management in the Classic Admin.

Any authenticated user with object editing rights can call this endpoin…
