From the WordPress 4.7.2 release post: WordPress versions 4.7.1 and earlier are affected by three security issues:
- 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.
WP_Queryis 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).
- A cross-site scripting (XSS) vulnerability was discovered in the posts list table. Reported by Ian Dunn of the WordPress Security Team.
