The Variation Swatches for WooCommerce plugin, in all versions starting at 1.0.8 up until 1.3.2, contains a vulnerability due to improper nonce verification in its settings reset functionality. The issue exists in the settings_init() function, which processes a reset action based on specific query parameters in the URL. The related delete_settings() function performs a faulty nonce validation check, making the reset operation insecure and susceptible to unauthorized access.

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

Unauth. Reflected Cross-Site Scripting (XSS) vulnerability in RadiusTheme Variation Swatches for WooCommerce plugin <= 2.3.7 versions.

The Variation Swatches for WooCommerce WordPress plugin is vulnerable to Stored Cross-Site Scripting via several parameters found in the ~/includes/class-menu-page.php file which allows attackers to inject arbitrary web scripts, in versions up to and including 2.1.1. Due to missing authorization checks on the tawcvs_save_settings function, low-level authenticated users such as subscribers can exploit this vulnerability.
