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.

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.

WordPress before 3.7.2 and 3.8.x before 3.8.2 allows remote authenticated users to publish posts by leveraging the Contributor role, related to wp-admin/includes/post.php and wp-admin/includes/class-wp-posts-list-table.php.

The wp_validate_auth_cookie function in wp-includes/pluggable.php in WordPress before 3.7.2 and 3.8.x before 3.8.2 does not properly determine the validity of authentication cookies, which makes it easier for remote attackers to obtain access via a forged cookie.

Multiple cross-site scripting (XSS) vulnerabilities in WordPress before 3.5.2 allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) uploads of media files, (2) editing of media files, (3) installation of plugins, (4) updates to plugins, (5) installation of themes, or (6) updates to themes.

WordPress before 3.5.2 allows remote attackers to read arbitrary files via an oEmbed XML provider response containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

WordPress before 3.5.2 does not properly check the capabilities of roles, which allows remote authenticated users to bypass intended restrictions on publishing and authorship reassignment via unspecified vectors.

The HTTP API in WordPress before 3.5.2 allows remote attackers to send HTTP requests to intranet servers via unspecified vectors, related to a Server-Side Request Forgery (SSRF) issue, a similar vulnerability to CVE-2013-0235.

WordPress before 3.5.2, when the uploads directory forbids write access, allows remote attackers to obtain sensitive information via an invalid upload request, which reveals the absolute path in an XMLHttpRequest error message.
