WordPress Blogs at Risk Due to Plug-In Flaw
A security flaw in the default configuration of a popular plug-in for WordPress has put blogs hosted on the platform at risk of data theft.
The flaw, discovered by researcher Jason Donenfeld, is in W3 Total Cache (W3TC), a plug-in to the blog-hosting platform that caches content in order to speed up request times.
Since data are stored similarly and in searchable form, Donenfeld says it's possible to extract sensitive information like password hashes and database cache keys from any directory that has been enabled. Even directories that aren't enabled wouldn't be very difficult to guess, a Seclist.org post on the matter said.
