datamodel-code-generator vulnerable to SSRF via JSON-Schema `$ref` to HTTP URL (silent by default)

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...

GHSA-5578-W22F-PFX9 datamodel-code-generator vulnerable to code injection via `x-python-import` / `customTypePath` in generated import statements

Summary A malicious input schema OpenAPI / JSON Schema can execute arbitrary Python code on the machine that imports the generated model. The x-python-import and customTypePath schema extensions flow, unsanitized, into the import statements datamodel-code-generator emits. A newline embedded in th...
