CVE-2021-46708 Open this link in a new tabHow to fix?
Upgrade swagger-ui-express to version 4.3.0 or higher.
Overview
swagger-ui-express is a module that allows you to serve auto-generated swagger-ui generated API docs from express, based on a swagger.json file.
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.
