+Hi Guys,
+
+Though it is not severe bug.But still some organizations take this seriously.
+
+Steps :
+
+1.Browse through your target.
+  say https://target.com
+2.Find a article or blog present on target website which must have a link to share that blog on different social networks such as
+  Facebook,Twitter etc.
+3.Let's say we got and article with url:
+  https://taget.com/how-to-hunt 
+  then just appened it with payload ?&u=https://attacker.com/vaya&text=another_site:https://attacker.com/vaya
+  so our url will become 
+  https://taget.com/how-to-hunt?&u=https://attacker.com/vaya&text=another_site:https://attacker.com/vaya
+4.Now hit enter with the abover url and just click on share with social media.
+  Just observe the content if it is including our payload i.e. https://attacker.com
+  Then it is vulnerable or else try next target.
