The developers of the popular content management system WordPress announced on Tuesday the availability of version 4.4.2, a release that patches a couple of security issues and many functionality bugs.
WordPress 4.4.2 fixes an open redirection vulnerability reported by Shailesh Suthar and a server-side request forgery (SSRF) affecting certain local URIs. The SSRF flaw was responsibly disclosed to the WordPress team by Denmark-based developer Ronni Skansing.
The latest version of WordPress also addresses 17 bugs affecting versions 4.4 and 4.4.1. WordPress users are advised to update their installations as soon as possible.
Security firm Sucuri reported on Monday that it had observed a spike in WordPress website infections. Attackers have been injecting malicious code into all the .js files of a targeted website in an effort to display ads and make a profit.
It’s unclear what method has been used by the hackers to compromise WordPress websites, but older versions of the CMS and its plugins are plagued by several vulnerabilities that can be exploited for this purpose.
For instance, WordPress released version 4.4.1 in January to address a cross-site scripting (XSS) vulnerability that developers said could allow malicious actors to compromise affected websites.
