{"cve":"CVE-2026-12128","nvd":{"published":"2026-08-15T03:16:46.970","modified":"2026-08-20T12:48:10.287","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-20"],"references":["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","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/2.9.9.6.8/addons/woocommerce/dopbsp-woocommerce.php#L141"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-12128","score":0.00613,"percentile":0.49355,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
