The `datamodel-code-generator` library (versions <= 0.61.0) is vulnerable to an unauthenticated path traversal and arbitrary local file read (CVE-2026-55389), allowing an attacker to supply a crafted JSON-Schema with `$ref` fields pointing to local files using `file://` URIs or `../` path traversal sequences, bypassing the `--no-allow-remote-refs` security control, which leads to information disclosure of sensitive data and enables filesystem mapping.
