DescriptionPimcore is an Open Source Data & Experience Management Platform. Prior to 11.5.19, 12.3.10, and 2026.1.6, the class-definition import endpoint /pimcore-studio/api/class/definition/configuration-view/detail/{id}/import accepts a DataObject field name that is emitted without an identifier allowlist by lib/DataObject/ClassBuilder/FieldDefinitionPropertiesBuilder.php into generated PHP properties and by models/DataObject/ClassDefinition/Helper/Dao.php into ALTER TABLE identifiers. An authenticated user with the objects permission can inject PHP syntax into the generated DataObject class, causing attacker-controlled code in generated var/classes/DataObject/.php files to run when an object of that class is instantiated, and can also inject SQL identifier content into schema-changing statements. The central models/DataObject/ClassDefinition/Data.php::setName() validation did not reject semicolons, braces, backticks, spaces, or other non-identifier characters. This issue is fixed in versions 11.5.19, 12.3.10, and 2026.1.6.
