WordPress fixes actively exploited flaw

A new WordPress version released Thursday fixes two critical cross-site scripting (XSS) vulnerabilities that could allow attackers to compromise websites.

One of the flaws is located in the Genericons icon font package that is used by several popular themes and plug-ins, including the default TwentyFifteen WordPress theme.

Researchers from Web security firm Sucuri warned Wednesday that they’ve already seen attacks targeting this XSS vulnerability.

To exploit it, attackers need to trick users to click on specifically crafted links, but once they do that, they can leverage the flaw to steal authentication cookies. If the victim is a website’s administrator, they could gain full control over that website.
