CVE-2026-55391: CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action in koxudaxi datamodel-code-generatorCVE-2026-55391 0 datamodel-code-generator generates Pydantic v2 models, dataclasses, TypedDict, and msgspec.Struct from OpenAPI, JSON Schema, GraphQL, Avro, Protobuf, and raw JSON, YAML, or CSV. Prior to 0.63.0, datamodel-code-generator validates a URL host once in src/datamodel_code_generator/http.py through get_body, _validate_url_for_fetch, and _get_ips_from_host, but then lets httpx resolve the host again for the connection, allowing DNS rebinding to bypass allow_private_network=False and reach internal services. This issue is fixed in version 0.63.0. Join the discussion | CVE Database V5 | 07/28/2026, 21:45:39 UTC Added: 07/28/2026, 21:52:41 UTC |
