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

- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 12.6.1
- Published: 2026-08-01 · Updated: 2026-08-03

## Affected

- pixelyoursite PixelYourSite – Your smart PIXEL (TAG) & API Manager: through 11.2.1
- pixelyoursite PixelYourSite Pro – Your smart PIXEL (TAG) Manager: fixed in 12.6.1

## 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.

## What to do

- Check your stack: if you ship or depend on pixelyoursite PixelYourSite – Your smart PIXEL (TAG) & API Manager, pixelyoursite PixelYourSite Pro – Your smart PIXEL (TAG) Manager, upgrade to a fixed version (12.6.1) per the references below.
