The `datamodel-code-generator` library is vulnerable to code injection (CVE-2026-54653) when generating Python models from attacker-controlled schemas (e.g., JSON Schema, OpenAPI, YAML). This occurs because the `default_factory` schema field's value is interpolated directly as a raw Python expression into the generated code, allowing an attacker who controls the input schema to achieve arbitrary Python code execution within the consumer's process at module import time, affecting developers or CI pipelines that process untrusted schemas.
