Synopsis

The remote Fedora host is missing a security update.

Description

Upstream announcement :

**WordPress 4.8.2 is now available**. This is a security release for all previous versions and we strongly encourage you to update your sites immediately.

WordPress versions 4.8.1 and earlier are affected by these security issues :

- $wpdb->prepare() can create unexpected and unsafe queries leading to potential SQL injection (SQLi).
WordPress core is not directly vulnerable to this issue, but we’ve added hardening to prevent plugins and themes from accidentally causing a vulnerability.
