Per the advice in this thread, I'm going to be deleting all plugins, fixing 4.2.0 and upgrading to 4.2.3 this morning; I am under the impression that a very likely culprit here is Yet Another Awards System, a plugin which, when I googled it, came back heavily associated with "SQL Injection."
It's a bit of a shame, though -- apparently we've used YAAS for many years to give badges and whatnot to members of the community. This is a shot in the dark, but does anyone know if those vulnerabilities have been patched by 4.2.3? Is there a good way to similarly overwrite the plugin's files without losing our data on who has what award and so forth?
