`datamodel-code-generator` vulnerable to code injection via unescaped carriage return in `--extra-template-data` `comment` field

Summary datamodel-code-generator is vulnerable to code injection when a developer passes an --extra-template-data file whose comment value contains a literal \r carriage return. The comment variable is rendered into a Python comment in six built-in templates with no line-terminator escaping...

`datamodel-code-generator` vulnerable to code injection in via attacker-controlled `default_factory` schema field

Summary datamodel-code-generator is vulnerable to code injection when generating Python models from an attacker-controlled JSON Schema, OpenAPI, YAML, JSON, Avro, Protobuf, or XSD schema. When a property carries a "defaultfactory" key, its value is interpolated verbatim — as a raw Python expressi...
