SCA: security update for datamodel-code-generator (GHSA-vx7x-vcc2-c44g)

high Tenable Self-Hosted Container Security Plugin ID 445430

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-55391)

Solution

Update the datamodel-code-generator library and its related packages to version 0.63.0 or later.
