Keycloak warning XML injection vulnerabilities

I always get the warning “XML External Entity switches are not supported. You may get XML injection vulnerabilities.” when using my saml client.
I already checked the code where the warning is coming from but I don’t know how to get rid of this warning. Is this warning harmless or should I do something about it?


Have you by any chance found the answer to your question?

I still haven’t found a solution or explanation for this.
