      <title>CVE-2026-12128 — Pinpoint Booking System &lt;= 2.9.9.6.8 - Unauthenticated Improper Input Validation to Price Manipulation via 'cart_data'…</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-12128</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; dotonpaper Pinpoint Booking System – Version 2&lt;/p&gt;
&lt;p&gt;The Pinpoint Booking System – Version 2 plugin for WordPress is vulnerable to Price Manipulation via the `cart_data` parameter in all versions up to, and including, 2.9.9.6.8. This is due to the `dopbsp_woocommerce_add_to_cart` AJAX action being registered via `wp_ajax_nopriv_*` with no authentication, no nonce verification, and no server-side recalculation of pricing — the `update` handler reads `price_total` directly from the attacker-controlled `cart_data` POST parameter and persists it to the database via `$wpdb-&amp;gt;insert()` without validating it against the calendar&amp;#39;s configured pricing. The `woocommerce_before_calculate_totals` callback subsequently reads the stored attacker-supplied value back from the database and passes it directly to `$product-&amp;gt;set_price()` without recomputing from calendar settings. This makes it possible for unauthenticated attackers to override the WooCommerce checkout price of any bookable product tied to a booking calendar to an arbitrary value, effectively enabling the purchase of any such product at a self-chosen price.&lt;/p&gt;</description>
