### 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)
```
