Upgrade datamodel-code-generator to version 0.60.2 or higher.
Overview
datamodel-code-generator is a Datamodel Code Generator
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements Used in a Template Engine via the comment field in the --extra-template-data. An attacker can execute arbitrary Python code during import by supplying a crafted extras file containing a carriage return in the comment value, which is rendered unescaped into generated Python code.
Note: This is only exploitable if the extras file used with --extra-template-data is influenced by attacker-controlled input.
