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

• Severity: medium (CVSS 5.3 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-01 · updated 2026-08-12
• Weakness: CWE-200

Description

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 woo_purchase 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.

Affected products

• PixelYourSite – Your smart PIXEL (TAG) & API Manager: through 11.2.1
• PixelYourSite Pro – Your smart PIXEL (TAG) Manager: before 12.6.1 — fixed in 12.6.1

How to fix

Upgrade to a fixed version: PixelYourSite Pro – Your smart PIXEL (TAG) Manager 12.6.1. Check the vendor advisory for mitigations.
