Description
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.
