WordPress Security January Roundup: Core XSS and 4 Plugin vulnerabilities

This has certainly been an eventful month in WordPress security. January 6th saw a WordPress core security update. Upgrade immediately to version 4.4.1 of WordPress core if you haven’t already.

The vulnerability that WordPress 4.4.1 fixes is a cross site scripting or XSS vulnerability. The Automattic team did not release details of the vulnerability in the announcement, but the patch was reverse engineered by several security teams and they used the code change to come up with a proof of concept exploit. The exploit has also been posted on twitter. The result is that the exploit for this security issue is now in the wild so it’s very important that you update asap.

The following plugins also had vulnerabilities reported and in most cases, fixed, this month:

If you have not updated the plugins above, do so immediately.

In other news, we will be releasing a beta of a major new version of Wordfence in the coming days. If you are interested in running a beta version of Wordfence to try out new features – and to help us test new releases – you can join our Wordfence Beta mailing list on this page.
