Hacking from a Wordpress comment email is it possible?

I got this spam in my WP comments

peeticrack@gmail.com /* <![CDATA[ */ (function(){try{var s,a,i,j,r,c,l=document.getElementById("__cf_email__");a=l.className;if(a){s='';r=parseInt(a.substr(0,2),16);for(j=2;a.length-j;j+=2){c=parseInt(a.substr(j,2),16)^r;s+=String.fromCharCode(c);}s=document.createTextNode(s);l.parentNode.replaceChild(s,l);}}catch(e){}})(); /* ]]> */

PHP:

It was placed in the email, there was no www and the comment look ok.

What does this "code" do?

 

It looks pretty pointless, is your WP patched to the latest version?

 

It's a function used for email address obfuscation. Nothing dangerous.
Patching your WP to the latest version is highly recommended anyway

 

Ahh i thought it was that but i did not know. I never seen they put it there before. Thanks

 

quite tough question. I would like to respond quickly.

 

I also have no any idea about it.

 

it is already answered
