CVE-2020-28039 3 Canonical, Debian, Wordpress 3 Ubuntu Linux, Debian Linux, Wordpress 2022-06-29 6.4 MEDIUM 9.1 CRITICAL
is_protected_meta in wp-includes/meta.php in WordPress before 5.5.2 allows arbitrary file deletion because it does not properly determine whether a meta key is considered protected.
CVE-2020-28032 3 Debian, Fedoraproject, Wordpress 3 Debian Linux, Fedora, Wordpress 2022-06-29 7.5 HIGH 9.8 CRITICAL
WordPress before 5.5.2 mishandles deserialization requests in wp-includes/Requests/Utility/FilteredIterator.php.
CVE-2020-28037 3 Debian, Fedoraproject, Wordpress 3 Debian Linux, Fedora, Wordpress 2022-04-28 7.5 HIGH 9.8 CRITICAL
is_blog_installed in wp-includes/functions.php in WordPress before 5.5.2 improperly determines whether WordPress is already installed, which might allow an attacker to perform a new installation, leading to remote code execution (as well as a denial of service for the old installation).
CVE-2020-28035 3 Debian, Fedoraproject, Wordpress 3 Debian Linux, Fedora, Wordpress 2022-04-28 7.5 HIGH 9.8 CRITICAL
WordPress before 5.5.2 allows attackers to gain privileges via XML-RPC.
CVE-2020-28036 3 Debian, Fedoraproject, Wordpress 3 Debian Linux, Fedora, Wordpress 2022-04-28 7.5 HIGH 9.8 CRITICAL
wp-includes/class-wp-xmlrpc-server.php in WordPress before 5.5.2 allows attackers to gain privileges by using XML-RPC to comment on a post.
CVE-2021-44223 1 Wordpress 1 Wordpress 2021-11-30 7.5 HIGH 9.8 CRITICAL
WordPress before 5.8 lacks support for the Update URI plugin header. This makes it easier for remote attackers to execute arbitrary code via a supply-chain attack against WordPress installations that use any plugin for which the slug satisfies the naming constraints of the WordPress.org Plugin Directory but is not yet present in that directory.
CVE-2016-10033 3 Joomla, Phpmailer Project, Wordpress 3 Joomla\!, Phpmailer, Wordpress 2021-09-30 7.5 HIGH 9.8 CRITICAL
The mailSend function in the isMail transport in PHPMailer before 5.2.18 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code via a \" (backslash double quote) in a crafted Sender property.
CVE-2016-10045 3 Joomla, Phpmailer Project, Wordpress 3 Joomla\!, Phpmailer, Wordpress 2021-09-30 7.5 HIGH 9.8 CRITICAL
The isMail transport in PHPMailer before 5.2.20 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code by leveraging improper interaction between the escapeshellarg function and internal escaping performed in the mail function in PHP. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-10033.
CVE-2020-36326 2 Phpmailer Project, Wordpress 2 Phpmailer, Wordpress 2021-06-14 7.5 HIGH 9.8 CRITICAL
PHPMailer 6.1.8 through 6.4.0 allows object injection through Phar Deserialization via addAttachment with a UNC pathname. NOTE: this is similar to CVE-2018-19296, but arose because 6.1.8 fixed a functionality problem in which UNC pathnames were always considered unreadable by PHPMailer, even in safe contexts. As an unintended side effect, this fix eliminated the code that blocked addAttachment exploitation.
CVE-2017-5611 3 Debian, Oracle, Wordpress 3 Debian Linux, Data Integrator, Wordpress 2021-01-30 7.5 HIGH 9.8 CRITICAL
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.
CVE-2019-17670 1 Wordpress 1 Wordpress 2020-09-11 7.5 HIGH 9.8 CRITICAL
WordPress before 5.2.4 has a Server Side Request Forgery (SSRF) vulnerability because Windows paths are mishandled during certain validation of relative URLs.
CVE-2019-20041 1 Wordpress 1 Wordpress 2020-01-08 7.5 HIGH 9.8 CRITICAL
wp_kses_bad_protocol in wp-includes/kses.php in WordPress before 5.3.1 mishandles the HTML5 colon named entity, allowing attackers to bypass input sanitization, as demonstrated by the javascript: substring.
CVE-2019-17669 1 Wordpress 1 Wordpress 2019-11-05 7.5 HIGH 9.8 CRITICAL
WordPress before 5.2.4 has a Server Side Request Forgery (SSRF) vulnerability because URL validation does not consider the interpretation of a name as a series of hex characters.
CVE-2018-20148 2 Debian, Wordpress 2 Debian Linux, Wordpress 2019-03-04 7.5 HIGH 9.8 CRITICAL
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.
CVE-2017-16510 1 Wordpress 1 Wordpress 2018-02-04 7.5 HIGH 9.8 CRITICAL
WordPress before 4.8.3 is affected by an issue where $wpdb->prepare() can create unexpected and unsafe queries leading to potential SQL injection (SQLi) in plugins and themes, as demonstrated by a "double prepare" approach, a different vulnerability than CVE-2017-14723.
CVE-2017-14723 1 Wordpress 1 Wordpress 2017-11-10 7.5 HIGH 9.8 CRITICAL
Before version 4.8.2, WordPress mishandled % characters and additional placeholder values in $wpdb->prepare, and thus did not properly address the possibility of plugins and themes enabling SQL injection attacks.
