Denial of Service in http-swagger

Impact

Allows an attacker to perform a DOS attack consisting of memory exhaustion on the host system.

Patches

Yes. Please upgrade to v1.2.6.

Workarounds

A workaround is to restrict the path prefix to the "GET" method. As shown below

func main() {
	r := mux.NewRouter()

	r.PathPrefix("/swagger/").Handler(httpSwagger.Handler(
		httpSwagger.URL("http://localhost:1323/swagger/doc.json"), //The url pointing to API definition
		httpSwagger.DeepLinking(true),
		httpSwagger.DocExpansion("none"),
		httpSwagger.DomID("#swagger-ui"),
	)).Methods(http.MethodGet)
