CVE-2026-18059: PixelYourSite <= 11.2.1 - Unauthenticated Sensitive Information Exposure via Order-Received Endpoint Missing Key Validation

The PixelYourSite – Your smart PIXEL (TAG) & API Manager plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.2.1 via the getWooPurchaseEventParams. This makes it possible for unauthenticated attackers to extract WooCommerce purchase metadata — including product names, product IDs, quantities, per-item prices, order totals, currency, and order/transaction IDs — for any existing order by supplying an invalid or arbitrary order key. This is exploitable against any known or enumerated order ID, as the plugin resolves the order from the URL path variable alone and emits the full woopurchase tracking payload into the page HTML via the pysOptions JavaScript object across its Facebook, Google Analytics, and Google Tag Manager integrations regardless of key validity.
