"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.
    Reported by Slavco

    discovered in the oEmbed discovery. Reported by xknown
