Alert meAnalysisAIv1 – Jul 16, 2026
Privilege escalation in the WPFunnels (Funnel Builder for WooCommerce) plugin for WordPress lets authenticated users holding the wpf_manage_funnels capability — typically the plugin's Funnel Manager custom role — rewrite the global wp_user_roles option and grant their own role full administrator capabilities. All versions up to and including 3.12.8 are affected, and Wordfence rates it CVSS 8.8 (High). No public exploit has been identified at time of analysis, but the root cause is trivial (an unvalidated option name reaching update_option()), making reliable weaponization straightforward for a low-privileged insider.

DescriptionCVE.org
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.
Executive ViewAI
WPFunnels plugin for WordPress (versions ≤3.12.8) contains a privilege escalation vulnerability allowing authenticated users with funnel-manager roles to escalate to full administrator access, compromising entire WordPress installations and sensitive business data. This impacts organizations using WPFunnels for e-commerce or marketing automation, particularly those with distributed administrative access. No vendor patch is available; immediate access restrictions are required to prevent insider threats.
Within 24 hours: Audit all user accounts assigned the wpf_manage_funnels capability and revoke it from non-essential users; document baseline role assignments. Within 7 days: Deploy monitoring to alert on wp_user_roles option modifications via security plugins or database auditing; implement policies restricting funnel-builder role assignment to select administrators. Within 30 days: Evaluate WPFunnels alternatives with granular role-based access controls, engage vendor regarding patch timeline, and prepare contingency to disable WPFunnels if no patch is committed within 60 days.
No vendor-released patch identified at time of analysis. Interim mitigations: (1) Restrict wpf_manage_funnels capability to only essential, verified administrators using WordPress role-management plugins; (2) Configure real-time alerts on wp_user_roles database modifications via security monitoring tools; (3) Enforce multi-factor authentication and IP whitelisting for all WordPress administrative accounts; (4) Disable WPFunnels if funnel operations are non-critical until patch is released.
