WordPress through 4.8.2, when domain-based flashmediaelement.swf sandboxing is not used, allows remote attackers to conduct cross-domain Flash injection (XSF) attacks by leveraging code contained within the wp-includes/js/mediaelement/flashmediaelement.swf file.
Before version 4.8.2, WordPress mishandled % characters and additional placeholder values in $wpdb->prepare, and thus did not properly address the possibility of plugins and themes enabling SQL injection attacks.
Cross-site scripting (XSS) vulnerability in platinum_seo_pack.php in the Platinum SEO plugin before 1.3.8 for WordPress allows remote attackers to inject arbitrary web script or HTML via the s parameter.
Cross-site scripting (XSS) vulnerability in login-with-ajax.php in the Login With Ajax (aka login-with-ajax) plugin before 3.0.4.1 for WordPress allows remote attackers to inject arbitrary web script or HTML via the callback parameter in a lostpassword action to wp-login.php.
