Description

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

Affected products

PPOM for WooCommerce: before 24.0 — fixed in 24.0

How to fix

Upgrade to a fixed version: PPOM for WooCommerce 24.0. Check the vendor advisory for mitigations.
