$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. A cross-site scripting (XSS) vulnerability was discovered in the oEmbed discovery. Reported by xknown of the WordPress Security Team. A cross-site scripting (XSS) vulnerability was discovered in the visual editor. Reported by Rodolfo Assis (@brutelogic) of Sucuri Security.
