{"id":"CVE-2026-12128","state":"PUBLISHED","title":"Pinpoint Booking System <= 2.9.9.6.8 - Unauthenticated Improper Input Validation to Price Manipulation via 'cart_data' Parameter","description":"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 `$wpdb->insert()` without validating it against the calendar's configured pricing. The `woocommerce_before_calculate_totals` callback subsequently reads the stored attacker-supplied value back from the database and passes it directly to `$product->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.","publishedAt":"2026-08-15T02:26:18.228Z","updatedAt":"2026-08-17T19:38:57.332Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["dotonpaper Pinpoint Booking System – Version 2"],"affected":[{"vendor":"dotonpaper","product":"Pinpoint Booking System – Version 2","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.9.9.6.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e6faf2b7-52e2-4656-9171-4ee17352ed1e?source=cve","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.8/addons/woocommerce/includes/class-woocommerce-cart.php#L293","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.8/addons/woocommerce/includes/class-woocommerce-cart.php#L90","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.8/addons/woocommerce/dopbsp-woocommerce.php#L141","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.8/addons/woocommerce/includes/class-woocommerce-cart.php#L125","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.7/addons/woocommerce/includes/class-woocommerce-cart.php#L293","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.7/addons/woocommerce/includes/class-woocommerce-cart.php#L90","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.7/addons/woocommerce/dopbsp-woocommerce.php#L141","https://plugins.trac.wordpress.org/browser/booking-system/tags/2.9.9.6.7/addons/woocommerce/includes/class-woocommerce-cart.php#L125"],"weaknesses":["CWE-20"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12128.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12128","state":"PUBLISHED","datePublished":"2026-08-15T02:26:18.228Z","dateUpdated":"2026-08-17T19:38:57.332Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-12T15:17:10.845Z"},"containers":{"cna":{"title":"Pinpoint Booking System <= 2.9.9.6.8 - Unauthenticated Improper Input Validation to Price Manipulation via 'cart_data' Parameter","descriptions":[{"lang":"en","value":"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.
