The make_clickable function in wp-includes/formatting.php in WordPress before 3.1.1 does not properly check URLs before passing them to the PCRE library, which allows remote attackers to cause a denial of service (crash) via a comment with a crafted URL that triggers many recursive calls.

Cross-site scripting (XSS) vulnerability in WordPress before 3.1.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The wp_create_nonce function in wp-includes/pluggable.php in WordPress 3.3.1 and earlier associates a nonce with a user account instead of a user session, which might make it easier for remote attackers to conduct cross-site request forgery (CSRF) attacks on specific actions and objects by sniffing the network, as demonstrated by attacks against the wp-admin/admin-ajax.php and wp-admin/user-new.php scripts. NOTE: the vendor reportedly disputes the significance of this issue because wp_create_nonce operates as intended, even if it is arguably inconsistent with certain CSRF protection details advocated by external organizations

wp-comments-post.php in WordPress before 3.3.2 supports offsite redirects, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via unspecified vectors.

wp-includes/formatting.php in WordPress before 3.3.2 attempts to enable clickable links inside attributes, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via unspecified vectors.

Plupload before 1.5.4, as used in wp-includes/js/plupload/ in WordPress before 3.3.2 and other products, enables scripting regardless of the domain from which the SWF content was loaded, which allows remote attackers to bypass the Same Origin Policy via crafted content.

Unspecified vulnerability in wp-includes/js/swfobject.js in WordPress before 3.3.2 has unknown impact and attack vectors.

wp-admin/plugins.php in WordPress before 3.3.2 allows remote authenticated site administrators to bypass intended access restrictions and deactivate network-wide plugins via unspecified vectors.

Cross-site scripting (XSS) vulnerability in swfupload.swf in SWFupload 2.2.0.1 and earlier, as used in WordPress before 3.5.2, TinyMCE Image Manager 1.1 and earlier, and other products allows remote attackers to inject arbitrary web script or HTML via the buttonText parameter, a different vulnerability than CVE-2012-3414.

wp-admin/setup-config.php in the installation component in WordPress 3.3.1 and earlier generates different error messages for requests lacking a dbname parameter depending on whether the MySQL credentials are valid, which makes it easier for remote attackers to conduct brute-force attacks via a series of requests with different uname and pwd parameters. NOTE: the vendor disputes the significance of this issue; also, it is unclear whether providing intentionally vague error messages during installation would be reasonable from a usability perspective
