Plug-In Flaw Puts WordPress Blogs at Risk
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.
At present, all versions of WordPress are vulnerable to the flaw, but a later post by Donenfeld said the author of the plug-in plans to close the gap soon. W3TC users are encouraged to disable the plug-in until such a fix is released.
WordPress, an extremely popular platform for hosting both personal and professional blogs, is used to run large and popular sites like BuzzFeed and Gawker.
