wp-includes/class-wp-customize-widgets.php in the widget implementation in WordPress 3.9.x before 3.9.2 might allow remote attackers to execute arbitrary code via crafted serialized data.

Cross-site scripting (XSS) vulnerability in wp-includes/pluggable.php in WordPress before 3.9.2, when Multisite is enabled, allows remote authenticated administrators to inject arbitrary web script or HTML, and obtain Super Admin privileges, via a crafted avatar URL.

wp-includes/pluggable.php in WordPress before 3.9.2 rejects invalid CSRF nonces with a different timing depending on which characters in the nonce are incorrect, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force attack.

wp-includes/pluggable.php in WordPress before 3.9.2 does not use delimiters during concatenation of action values and uid values in CSRF tokens, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force attack.

The Incutio XML-RPC (IXR) Library, as used in WordPress before 3.9.2 and Drupal 6.x before 6.33 and 7.x before 7.31, permits entity declarations without considering recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.

Multiple cross-site scripting (XSS) vulnerabilities in videoplayer/autoplay.php in the HTML5 Video Player with Playlist plugin 2.4.0 and earlier for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) theme or (2) playlistmod parameter.

Multiple cross-site scripting (XSS) vulnerabilities in contact/edit.php in the WP Ultimate Email Marketer plugin 1.1.0 and earlier for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) listname or (2) contact parameter.
