TL;DR

A backend user holding the classes permission can define a DataObject class whose field name or class name/ID is written unescaped into the generated PHP class file and into ALTER TABLE DDL. Class name/ID validation uses an unanchored identifier regex, so extra characters pass the check, and the class ID is concatenated unquoted into raw SQL table names when loading DataObject field data. A crafted field name reaches arbitrary PHP execution once the generated class file is autoloaded, and a crafted class ID leads to SQL injection. The fix anchors the identifier validation regex to the full name/ID and quotes the constructed table and index identifiers before use.
