I'm triying to query FullPhotoUrl from an User object and creating a PageReference for that URL. But this runs me into the security scan issue URL Redirection Attack.

Can someone please help me to fix this?

String userId = String.escapeSingleQuotes(Apexpages.currentpage().getparameters().get('ID'));
list<User> lstUsers = [select FullPhotoUrl from User where Id=:userId limit 1];
String strPhotoURL = lstUsers[0].FullPhotoUrl;

strPhoto = EncodingUtil.base64encode(new PageReference(strPhotoURL).getContent());

Thank you in advance!
