WordPress Publishes Critical Security Update XSS, SQL Injection vulnerabilities

WordPress 4.7.1 and earlier forms are influenced by various vulnerabilities. A remote attacker could exploit some of these vulnerabilities to take control of an infected site.

WordPress 4.7.2 is currently accessible. This is a security update for every single past version and WordPress strongly urge you to upgrade your website quickly.

WordPress versions 4.7.1 and prior are influenced by three security issues:

  1. The user interface for assigning taxonomy terms in Press This is shown to users who do not have permissions to use it. Reported by David Herrera of Alley Interactive.
  2. WP_Query is vulnerable to a SQL injection (SQLi) when passing unsafe data. WordPress core is not directly vulnerable to this issue, but we’ve added hardening to prevent plugins and themes from accidentally causing a vulnerability. Reported by Mo Jangda (batmoo).
  3. A cross-site scripting (XSS) vulnerability was discovered in the posts list table. Reported by Ian Dunn of the WordPress Security Team.
