description

WP User Manager versions before 2.9.20 may retain a functional WordPress account after a payment-gated registration does not complete payment. An unauthenticated user may obtain an account without completing the required payment when payment-gated registration is enabled.

mitigation

Update WP User Manager to version 2.9.20 or later. Until upgraded, disable payment-gated registration or restrict access to registration endpoints.

fixed in 2.9.20
