Summary datamodel-code-generator's built-in HTTP fetcher http.get body issues an httpx.GET against any URL passed to --url or reached via a redirect chain with no allow-list, no deny-list, no IP/host validation, and follow redirects=True. Loopback addresses, RFC1918 ranges, link-local...

Summary datamodel-code-generator honours a custom x-python-type JSON-Schema extension that lets a schema author override the generated Python type for a field. The value is forwarded verbatim into the generated Python source as the field annotation, with a single sanitisation pass that is trivial...

PT-2026-65651

Summary JSON-Schema $ref values pointing at HTTP or HTTPS URLs are silently dereferenced by datamodel-code-generator with no IP/host validation, no scheme allow-list, and redirects followed unconditionally. The --allow-remote-refs gate added in 0.56.0 defaults to None, which only emits a...

Summary When generating models from an XML Schema --input-file-type xmlschema, datamodel-code-generator resolves , , , and schemaLocation attributes against the source directory and reads the target with no restriction to the input/base directory. An attacker who controls the input XSD can read...

PT-2026-65638

Summary datamodel-code-generator is vulnerable to code injection when generating Python models from an attacker-controlled JSON Schema, OpenAPI, YAML, JSON, Avro, Protobuf, or XSD schema. When a property carries a "default factory" key, its value is interpolated verbatim — as a raw Python...

PT-2026-65664

Summary When datamodel-code-generator fetches a remote schema and follows an HTTP redirect, it re-sends the original request headers, including any Authorization header, to the redirect target even when the redirect changes origin host/port/scheme. Credentials that an operator scoped to a trusted...

CVE-2026-54690: Server-Side Request Forgery (SSRF)

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. From 0.9.1 until 0.61.0, datamodel-code-generator silently dereferences attacker-controlled JSON Schema $ref HTTP or...

CVE-2026-55390: Improper Limitation of a Pathname to a Restricted Directory

datamodel-code-generator generates Python data models from schema definitions. From 0.59.0 until 0.62.0, XML Schema parsing in src/datamodelcodegenerator/parser/xmlschema.py for --input-file-type xmlschema resolves xs:include, xs:import, xs:redefine, and xs:override schemaLocation values outside...

PT-2026-65648

Summary datamodel-code-generator resolves JSON-Schema $ref targets that point at the local filesystem without restricting them to the input/base directory and without honoring the remote-reference security control. In the default configuration, an attacker who controls an input schema a "paste yo...

CVE-2026-17501

A flaw was found in llama.cpp. A remote attacker could exploit a vulnerability in the JSON-Schema-to-GBNF Conversion component, specifically within the transform function. This flaw allows for the manipulation of resource allocation, which can lead to a denial of service DoS by exhausting availab...

CVE-2026-57916

proCertum SmartSign opens Certificate Practice Statement CPS URI without schema validation. An attacker can prepare arbitrary certificate with CPS URI pointing to a local executable file or any URL, sign a document with it, and send it to the victim. When the victim opens the document in the...
