Datamodel-Code-Generator

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.

The `datamodel-code-generator` tool is vulnerable to a Server-Side Request Forgery (SSRF) protection bypass, identified as CVE-2026-55391, due to a time-of-check/time-of-use (TOCTOU) race condition through DNS rebinding, allowing attackers to access internal services like cloud instance metadata endpoints when processing attacker-influenced URLs.
