CVE-2026-15103— WPFunnels <= 3.12.8 - Authenticated (Funnel Manager+) Privilege Escalation via 'group_id' Path Parameter

WPFunnels <= 3.12.8 - Authenticated (Funnel Manager+) Privilege Escalation via 'group_id' Path Parameter

The WPFunnels – Funnel Builder for WooCommerce with Checkout & One Click Upsell plugin for WordPress is vulnerable to Privilege Escalation via arbitrary option update in all versions up to, and including, 3.12.8. This is due to the `update_settings()` REST callback failing to validate the `group_id` path parameter against an allowlist of permitted option names before passing it directly to `get_option()` and `update_option()`, allowing the built-in `wp_user_roles` option — which satisfies the route's loose `[\w-]+` regex — to be targeted. This makes it possible for authenticated attackers with the `wpf_manage_funnels` capability and above to elevate their privileges to administrator by writing a crafted role definition containing arbitrary capabilities into the `wp_user_roles` option, thereby granting any WordPress role full site administrator access. The `wpf_manage_funnels` capability is typically assigned to the Funnel Manager custom role created by the plugin, meaning this role is the minimum required to exploit the vulnerability.

特权管理不恰当

WordPress WPFunnels 权限许可和访问控制问题漏洞

WordPress WPFunnels是WordPress基金会的一款能够提升平均订单价值和转化率的 WooCommerce 销售漏斗构建工具。 WordPress WPFunnels 3.12.8及之前版本存在权限许可和访问控制问题漏洞，该漏洞源于`update_settings()` REST回调未能对`group_id`路径参数进行允许列表验证，直接传递参数至`get_option()`和`update_option()`，导致攻击者可通过写入特制的角色定义到`wp_user_roles`选项中来提
