This is due to the `maybe_update_user_role()` function reading the target role directly from an attacker-controlled Gravity Forms entry field \u2014 configured via the feed's `user_role_field_id` \u2014 and passing it to `WP_User::set_role()` without validating the supplied value against an allowlist of permitted roles. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to administrator by tampering with the hidden role field value at form submission time. Exploitation is further enabled by the fact that $0 orders are synchronously marked as SUCCESS during form submission without requiring a real payment, and when no GF User Registration user can be resolved, the role assignment target falls back to `$lead['created_by']` \u2014 the currently authenticated submitter's own user ID \u2014 making any authenticated form submitter an eligible exploitation target."}], "lastModified": "2026-09-25T14:17:21.750", "sourceIdentifier": "security@wordfence.com"}
