xmlrpc (xmlrpc.php) in WordPress 2.1.2, and probably earlier, allows remote authenticated users with the contributor role to bypass intended access restrictions and invoke the publish_posts functionality, which can be used to "publish a previously saved post."

Multiple cross-site scripting (XSS) vulnerabilities in the Sniplets 1.1.2 and 1.2.2 plugin for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) text parameter to (a) warning.php, (b) notice.php, and (c) inset.php in view/sniplets/, and possibly (d) modules/execute.php; the (2) url parameter to (e) view/admin/submenu.php; and the (3) page parameter to (f) view/admin/pager.php.

WordPress before 2.0.5 does not properly store a profile containing a string representation of a serialized object, which allows remote authenticated users to cause a denial of service (application crash) via a string that represents a (1) malformed or (2) large serialized object, because the object triggers automatic unserialization for display.

Cross-site scripting (XSS) vulnerability in wp-db-backup.php in WordPress 2.0.11 and earlier, and possibly 2.1.x through 2.3.x, allows remote attackers to inject arbitrary web script or HTML via the backup parameter in a wp-db-backup.php action to wp-admin/edit.php.

NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

wp-admin/options.php in WordPress MU before 1.3.2, and WordPress 2.3.2 and earlier, does not properly validate requests to update an option, which allows remote authenticated users with manage_options and upload_files capabilities to execute arbitrary code by uploading a PHP script and adding this script's pathname to active_plugins.

Unrestricted file upload vulnerability in the wp_check_filetype function in wp-includes/functions.php in WordPress before 2.8.6, when a certain configuration of the mod_mime module in the Apache HTTP Server is enabled, allows remote authenticated users to execute arbitrary code by posting an attachment with a multiple-extension filename, and then accessing this attachment via a direct request to a wp-content/uploads/ pathname, as demonstrated by a .php.jpg filename.

Cross-site request forgery (CSRF) vulnerability in deans_permalinks_migration.php in the Dean's Permalinks Migration 1.0 plugin for WordPress allows remote attackers to modify the oldstructure (aka dean_pm_config[oldstructure]) configuration setting as administrators via the old_struct parameter in a deans_permalinks_migration.php action to wp-admin/options-general.php, as demonstrated by placing an XSS sequence in this setting.

Cross-site scripting (XSS) vulnerability in wp-newblog.php in WordPress multi-user (MU) 1.0 and earlier allows remote attackers to inject arbitrary web script or HTML via the weblog_id parameter (Username field).

Multiple cross-site request forgery (CSRF) vulnerabilities in math-comment-spam-protection.php in the Math Comment Spam Protection 2.1 and earlier plugin for WordPress allow remote attackers to perform actions as administrators via the (1) mcsp_opt_msg_no_answer or (2) mcsp_opt_msg_wrong_answer parameter to wp-admin/options-general.php.

Multiple cross-site scripting (XSS) vulnerabilities in captcha\captcha.php in the Captcha! 2.5d and earlier plugin for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) captcha_ttffolder, (2) captcha_numchars, (3) captcha_ttfrange, or (4) captcha_secret parameter.

Multiple SQL injection vulnerabilities in Wordpress before 2.2.3 and Wordpress multi-user (MU) before 1.2.5a allow remote attackers to execute arbitrary SQL commands via the post_type parameter to the pingback.extensions.getPingbacks method in the XMLRPC interface, and other unspecified parameters related to "early database escaping" and missing validation of "query string like parameters."
