Vulnerability Details

SwaggerUI supports displaying remote OpenAPI definitions through the ?url parameter. This enables robust demonstration capabilities on sites like petstore.swagger.io, editor.swagger.io, and similar sites, where users often want to see what their OpenAPI definitions would look like rendered.

However, 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.

Resolution:
We've made the decision to disable query parameters (#4872) by default starting with SwaggerUI version 4.1.3. Please update to this version when it becomes available (ETA: 2021 December). Users will still be able to be re-enable the options at their discretion. We'll continue to enable query parameters on the Swagger demo sites.
