The WooCommerce Affiliate Plugin WordPress plugin before 4.16.4.5 does not have authorization and CSRF checks on a specific action handler, as well as does not sanitize its settings, which enables an unauthenticated attacker to inject malicious XSS payloads into the settings page of the plugin.
Authenticated Stored Cross-Site Scripting (XSS) vulnerability in YITH Maintenance Mode (WordPress plugin) versions <= 1.3.7, vulnerable parameter &yith_maintenance_newsletter_submit_label. Possible even when unfiltered HTML is disallowed by WordPress configuration.
An arbitrary file upload vulnerability in the YITH WooCommerce Gift Cards Premium plugin before 3.3.1 for WordPress allows remote attackers to achieve remote code execution on the operating system in the security context of the web server. In order to exploit this vulnerability, an attacker must be able to place a valid Gift Card product into the shopping cart. An uploaded file is placed at a predetermined path on the web server with a user-specified filename and extension. This occurs because the ywgc-upload-picture parameter can have a .php value even though the intention was to only allow uploads of Gift Card images.
The yith-maintenance-mode plugin before 1.2.0 for WordPress has CSRF with resultant XSS via the wp-admin/themes.php?page=yith-maintenance-mode panel_page parameter.
