`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. Python's tokenizer treats a bare CR as a physical-line ...
