CVE-2023-5419

Estado: ModificadaMedia (4.3)—

El complemento Funnelforms Free para WordPress es vulnerable a modificaciones no autorizadas de datos debido a una falta de verificación de capacidad en la función fnsf_af2_test_mail en versiones hasta la 3.4 incluida. Esto hace posible que atacantes autenticados, con permisos de nivel de suscriptor y superiores, envíen correos electrónicos de prueba a una dirección de correo electrónico arbitraria.
