WordPress — свободно распространяемая система управления содержимым сайта с открытым исходным кодом.

Cross-site scripting (XSS) vulnerability in swfupload.swf in SWFUpload 2.2.0.1 and earlier, as used in WordPress before 3.3.2, TinyMCE Image Manager 1.1, and other products, allows remote attackers to inject arbitrary web script or HTML via the movieName parameter, related to the "ExternalInterface.call" function.

Cross-site scripting (XSS) vulnerability in the MF Gig Calendar plugin 0.9.2 for WordPress allows remote attackers to inject arbitrary web script or HTML via the query string to the calendar page.

Cross-site scripting (XSS) vulnerability in assets/player.swf in the Audio Player plugin before 2.0.4.6 for Wordpress allows remote attackers to inject arbitrary web script or HTML via the playerID parameter.

The default configuration of SWFUpload in WordPress before 3.5.2 has an unrestrictive security.allowDomain setting, which allows remote attackers to bypass the Same Origin Policy and conduct cross-site scripting (XSS) attacks via a crafted web site.

The wp_ajax_update_plugin function in wp-admin/includes/ajax-actions.php in WordPress before 4.6 makes a get_plugin_data call before checking the update_plugins capability, which allows remote authenticated users to bypass intended read-access restrictions via the plugin parameter to wp-admin/admin-ajax.php, a related issue to CVE-2016-6896.

Directory traversal vulnerability in the get_category_template function in wp-includes/theme.php in WordPress 2.3.3 and earlier, and 2.5, allows remote attackers to include and possibly execute arbitrary PHP files via the cat parameter in index.php. NOTE: some of these details are obtained from third party information.

WordPress 2.6.3 relies on the REQUEST superglobal array in certain dangerous situations, which makes it easier for remote attackers to conduct delayed and persistent cross-site request forgery (CSRF) attacks via crafted cookies, as demonstrated by attacks that (1) delete user accounts or (2) cause a denial of service (loss of application access). NOTE: this issue relies on the presence of an independent vulnerability that allows cookie injection.

Cross-site scripting (XSS) vulnerability in the self_link function in in the RSS Feed Generator (wp-includes/feed.php) for WordPress before 2.6.5 allows remote attackers to inject arbitrary web script or HTML via the Host header (HTTP_HOST variable).

Open redirect vulnerability in wp-admin/upgrade.php in WordPress, probably 2.6.x, allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the backto parameter.

wp-admin/upgrade.php in WordPress, probably 2.6.x, allows remote attackers to upgrade the application, and possibly cause a denial of service (application outage), via a direct request.
