Cross-site scripting (XSS) vulnerability in wp-includes/wp-db.php in WordPress before 4.2.2 allows remote attackers to inject arbitrary web script or HTML via a long comment that is improperly stored because of limitations on the MySQL TEXT data type. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-3440.

Cross-site scripting (XSS) vulnerability in the user list table in WordPress before 4.3.1 allows remote authenticated users to inject arbitrary web script or HTML via a crafted e-mail address, a different vulnerability than CVE-2015-5714.

The sanitize_widget_instance function in wp-includes/class-wp-customize-widgets.php in WordPress before 4.2.4 does not use a constant-time comparison for widgets, which allows remote attackers to conduct a timing side-channel attack by measuring the delay before inequality is calculated.

SQL injection vulnerability in the wp_untrash_post_comments function in wp-includes/post.php in WordPress before 4.2.4 allows remote attackers to execute arbitrary SQL commands via a comment that is mishandled after retrieval from the trash.

Multiple cross-site scripting (XSS) vulnerabilities in WordPress before 4.1.2, when MySQL is used without strict mode, allow remote attackers to inject arbitrary web script or HTML via a (1) four-byte UTF-8 character or (2) invalid character that reaches the database layer, as demonstrated by a crafted character in a comment.

WordPress before 4.2.3 does not properly verify the edit_posts capability, which allows remote authenticated users to bypass intended access restrictions and create drafts by leveraging the Subscriber role, as demonstrated by a post-quickdraft-save action to wp-admin/post.php.

Cross-site scripting (XSS) vulnerability in WordPress before 4.2.3 allows remote authenticated users to inject arbitrary web script or HTML by leveraging the Author or Contributor role to place a crafted shortcode inside an HTML element, related to wp-includes/kses.php and wp-includes/shortcodes.php.

Cross-site scripting (XSS) vulnerability in wp-includes/wp-db.php in WordPress before 4.2.1 allows remote attackers to inject arbitrary web script or HTML via a long comment that is improperly stored because of limitations on the MySQL TEXT data type.

Cross-site scripting (XSS) vulnerability in example.html in Genericons before 3.3.1, as used in WordPress before 4.2.2, allows remote attackers to inject arbitrary web script or HTML via a fragment identifier.

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, does not limit the number of elements in an XML document, which allows remote attackers to cause a denial of service (CPU consumption) via a large document, a different vulnerability than CVE-2014-5265.

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.

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 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.

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.
