CWE-918  (opens in a new tab)

How to fix?

Upgrade swagger-ui-dist to version 4.1.3 or higher.

Overview

swagger-ui-dist is a module that exposes Swagger-UI's entire dist folder as a dependency-free npm module. Use swagger-ui instead, if you'd like to have npm install dependencies for you.

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the ?url parameter, which was intended to allow displaying remote OpenAPI definitions. This functionality may pose a risk for users who host their own SwaggerUI instances. In particular, including remote OpenAPI definitions opens a vector for phishing attacks by abusing the trusted names/domains of self-hosted instances.

NOTE: This vulnerability has also been identified as: CVE-2018-25031
