PPOM for WooCommerce <= 23.9 - Missing Authorization to Stored Cross-Site Scripting

Missing Authorization
CVE CVE-2021-25018
CVSS 5.4 (Medium)
Publicly Published January 17, 2022
Last Updated November 24, 2022
Researcher Krzysztof Zając


The PPOM for WooCommerce WordPress plugin before 24.0 does not have authorisation and CSRF checks in the ppom_settings_panel_action AJAX action, allowing any authenticated to call it and set arbitrary settings. Furthermore, due to the lack of sanitisation and escaping, it could lead to Stored XSS issues
