I have worked on resolving issues with a website that was hacked in early Feb 2015. Malicious code was inserted into the Sociable plugin as the file:
images/option2/.view27.php
I do not know if there is any connection with the reported vulnerability but it would be good to know that this vulnerability has been addressed. Site is using version 4.3.4.1
Thanks.
Confirm the same two errors as QuietNoise. I think this plugin is not quite ready for prime time as of this post. Too bad.
