Refitter: Unrestricted OpenAPI references permit build-host SSRF and file inclusion

Özet

Türkçe özeti henüz hazır değil; şimdilik kaynağın kendi açıklamasını gösteriyoruz.

Refitter is a tool for generating a C# REST API client using the Refit library. Prior to 2.1.1, the refitter dotnet tool invokes NJsonSchema with unsafe defaults for $ref resolution when generating Refit interfaces and contracts from attacker-controlled or attacker-influenced OpenAPI descriptions. Remote http(s) references cause requests from the developer or CI host and inline untrusted remote schema content into generated output. Absolute local file paths and relative ../ traversal outside the input directory also resolve and inline local content, permitting arbitrary local-file disclosure. The demonstrated chain stops at server-side request forgery, remote file inclusion, and local file inclusion, not code execution: Refit sets the base URL at runtime, enum values use verbatim-string doubling, and string defaults are escaped. This issue is fixed in version 2.1.1.
