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

WordPress 4.8.2 stores cleartext wp_signups.activation_key values (but stores the analogous wp_users.user_activation_key values as hashes), which might make it easier for remote attackers to hijack unactivated user accounts by leveraging database read access (such as access gained through an unspecified SQL injection vulnerability).

The register_routes function in wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php in the REST API in WordPress 4.7.x before 4.7.2 does not require an integer identifier, which allows remote attackers to modify arbitrary pages via a request for wp-json/wp/v2/posts followed by a numeric value and a non-numeric value, as demonstrated by the wp-json/wp/v2/posts/123?id=123helloworld URI.

Multiple cross-site scripting (XSS) vulnerabilities in userperspan.php in the Count Per Day module before 3.2 for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) page, (2) datemin, or (3) datemax parameter.

Cross-site scripting (XSS) vulnerability in map/map.php in the Count Per Day module before 3.1.1 for WordPress allows remote attackers to inject arbitrary web script or HTML via the map parameter.

Absolute path traversal vulnerability in download.php in the Count Per Day module before 3.1.1 for WordPress allows remote attackers to read arbitrary files via the f parameter.

In WordPress before 4.9.9 and 5.x before 5.0.1, authors could modify metadata to bypass intended restrictions on deleting files.

SQL injection vulnerability in wp-includes/class-wp-query.php in WP_Query in WordPress before 4.7.2 allows remote attackers to execute arbitrary SQL commands by leveraging the presence of an affected plugin or theme that mishandles a crafted post type name.

WordPress through 5.0.3 allows Path Traversal in wp_crop_image(). An attacker (who has privileges to crop an image) can write the output image to an arbitrary directory via a filename containing two image extensions and ../ sequences, such as a filename ending with the .jpg?/../../file.jpg substring.

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.

WordPress before 4.9.9 and 5.x before 5.0.1 allows remote code execution because an _wp_attached_file Post Meta entry can be changed to an arbitrary string, such as one ending with a .jpg?file.php substring. An attacker with author privileges can execute arbitrary code by uploading a crafted image containing PHP code in the Exif metadata. Exploitation can leverage CVE-2019-8943.
