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

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.

The _httpsrequest function (Snoopy/Snoopy.class.php) in Snoopy 1.2.3 and earlier, as used in (1) ampache, (2) libphp-snoopy, (3) mahara, (4) mediamate, (5) opendb, (6) pixelpost, and possibly other products, allows remote attackers to execute arbitrary commands via shell metacharacters in https URLs.

WordPress through 4.9.6 allows Author users to execute arbitrary code by leveraging directory traversal in the wp-admin/post.php thumb parameter, which is passed to the PHP unlink function and can delete the wp-config.php file. This is related to missing filename validation in the wp-includes/post.php wp_delete_attachment function. The attacker must have capabilities for files and posts that are normally available only to the Author, Editor, and Administrator roles. The attack methodology is to delete wp-config.php and then launch a new installation process to increase the attacker's privileges.
