Description

WordPress, a web blogging tool, was affected by an issue where $wpdb->prepare() can create unexpected and unsafe queries leading to potential SQL injection (SQLi) in plugins and themes, as demonstrated by a 'double prepare' approach, a different vulnerability than CVE-2017-14723.

For Debian 7 'Wheezy', these problems have been fixed in version 3.6.1+dfsg-1~deb7u18.

We recommend that you upgrade your wordpress packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
