Overview

dio is a powerful HTTP networking package for Dart/Flutter, supports Global configuration, Interceptors, FormData, Request cancellation, File uploading/downloading, Timeout, Custom adapters, Transformers, etc.

Affected versions of this package are vulnerable to CRLF Injection due to insufficient checks in the dio/lib/src/dio_mixin.dart package, if the attacker controls the HTTP method string.
