datamodel-code-generator vulnerable to SSRF protection bypass via DNS rebinding

Summary datamodel-code-generator's anti-SSRF guard validates the resolved IP of a fetch target once and then lets httpx perform its own independent DNS resolution to connect, so the validated address is never pinned. A hostname that resolves to a public IP at validation time and a private IP at...

CVE-2026-55391

CVE-2026-55391 affects the datamodel-code-generator project. Prior to version 0.63.0, the tool validates a URL host in http.py via get_body, _validate_url_for_fetch, and _get_ips_from_host, but then allows httpx to resolve the host again for the connection, enabling DNS rebinding to bypass allow_...
