The YITH WooCommerce Gift Cards plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'save_mail_status' and 'save_email_settings' functions in all versions up to, and including, 4.12.0. This makes it possible for unauthenticated attackers to modify WooCommerce settings.

Missing Authorization vulnerability in YITH YITH WooCommerce Gift Cards Premium.This issue affects YITH WooCommerce Gift Cards Premium: from n/a through 3.23.1.

Unauth. Arbitrary File Upload vulnerability in YITH WooCommerce Gift Cards premium plugin <= 3.19.0 on WordPress.

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.

plugin-fw/lib/yit-plugin-panel-wc.php in the YIT Plugin Framework through 3.3.8 for WordPress allows authenticated options changes.
