{"cve":"CVE-2026-84908","nvd":{"published":"2026-09-09T06:17:18.147","modified":"2026-09-09T15:33:34.467","status":"Deferred","description":"The WPFunnels plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.12.13. This is due to the plugin registering the 'wpfnl_load_payment' AJAX action for both authenticated and unauthenticated (wp_ajax_nopriv_) users and the underlying add_offer_product_to_cart() function performing no nonce verification, no capability check, and no validation that the attacker-supplied product_id is the offer product actually configured on the attacker-supplied step_id. This makes it possible for unauthenticated attackers to add arbitrary WooCommerce products to a cart at any discounted price configured on any funnel step, enabling price manipulation and revenue loss at checkout.","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-862"],"references":["https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.12/includes/core/offer/class-wpfnl-offer.php#L166","https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.12/includes/core/offer/class-wpfnl-offer.php#L213","https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.12/includes/core/offer/class-wpfnl-offer.php#L71","https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.13/includes/core/offer/class-wpfnl-offer.php#L166","https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.13/includes/core/offer/class-wpfnl-offer.php#L213"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-84908","score":0.00423,"percentile":0.36606,"date":"2026-11-01"},"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).
