Administrator escalation via unrestricted option-name update
Published Jul 16, 2026 · Updated Jul 16, 2026
Privilege escalation in WPFunnels 3.12.8 and earlier allows remote authenticated users with Funnel Manager access to become administrators. The update_settings() REST callback passes the unchecked group_id path value to get_option() and update_option(), so wp_user_roles can be overwritten with attacker-defined capabilities. The wpf_manage_funnels capability, normally assigned to the Funnel Manager role, is the minimum gate, and successful exploitation grants full site-administrator access.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
