<p>With more than 30 percent of the web currently powered by WordPress, it remains an attractive target for attackers. These two vulnerabilities in the Orbit Fox plugin —a cross-site scripting flaw and a privilege-escalation bug with a CVSS bug-severity score of 9.9— together could allow attackers the ability to inject malicious Javascript code into exposed websites with the goal of taking over control of them. Attackers can then plant malware, steal data and hijack users to nefarious sites. Such techniques have been used to launch Magecart attacks against thousands of e-commerce sites resulting in the theft of millions of credit card numbers.</p>
