How to fix?

Upgrade io.swagger:swagger-codegen to version 2.2.3 or higher.

Overview

io.swagger:swagger-codegen is a simple yet powerful representation of your RESTful API.

Affected versions of this package are vulnerable to Arbitrary Code Execution via the yaml parsing functionality. When a maliciously crafted yaml Open-API specification is parsed, it is possible to execute arbitrary code on the hosting server. This in particular, affects the 'generate' and 'validate' command in swagger-codegen (<= 2.2.2) and can lead to arbitrary code being executed when these commands are used on a well-crafted yaml specification.
