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

In WordPress before 4.7.3 (wp-admin/js/tags-box.js), there is cross-site scripting (XSS) via taxonomy term names.

In WordPress before 4.9.9 and 5.x before 5.0.1, authors could bypass intended restrictions on post types via crafted input.

In WordPress before 4.9.9 and 5.x before 5.0.1, contributors could conduct PHP object injection attacks via crafted metadata in a wp.getMediaItem XMLRPC call. This is caused by mishandling of serialized data at phar:// URLs in the wp_get_attachment_thumb_file function in wp-includes/post.php.

Cross-site scripting (XSS) vulnerability in skysa-official/skysa.php in Skysa App Bar Integration plugin, possibly before 1.04, for WordPress allows remote attackers to inject arbitrary web script or HTML via the submit parameter.

Cross-site scripting (XSS) vulnerability in the Ad-minister plugin 0.6 and earlier for WordPress allows remote attackers to inject arbitrary web script or HTML via the key parameter in a delete action to wp-admin/tools.php.

Cross-site scripting (XSS) vulnerability in adminimize/adminimize_page.php in the Adminimize plugin before 1.7.22 for WordPress allows remote attackers to inject arbitrary web script or HTML via the page parameter.

Multiple SQL injection vulnerabilities in VastHTML Forum Server (aka ForumPress) plugin 1.6.1 and 1.6.5 for WordPress allow remote attackers to execute arbitrary SQL commands via the (1) search_max parameter in a search action to index.php, which is not properly handled by wpf.class.php, (2) id parameter in an editpost action to index.php, which is not properly handled by wpf-post.php, or (3) topic parameter to feed.php.

In WordPress through 4.9.2, unauthenticated attackers can cause a denial of service (resource consumption) by using the large list of registered .js files (from wp-includes/script-loader.php) to construct a series of requests to load every file many times.

Before WordPress 4.9.5, the version string was not escaped in the get_the_generator function, and could lead to XSS in a generator tag.

** DISPUTED ** Cross-site scripting (XSS) vulnerability in lanoba-social-plugin/index.php in the Lanoba Social plugin 1.0 for WordPress allows remote attackers to inject arbitrary web script or HTML via the action parameter. NOTE: the vendor disputes this issue, stating "Lanoba's plug in does sanitize user input, and because that input is never sent to the browser, an attacker has no way of executing script or code on a user's behalf."
