This is due to missing capability checks on the connect() and listen_for_tokens() methods of the FormLift_Infusionsoft_Manager class, both of which are hooked to 'plugins_loaded' and execute on every page load. The connect() function generates an OAuth connection password and leaks it in the redirect Location header without verifying the requesting user is authenticated or authorized. The listen_for_tokens() function only validates the temporary password but performs no user authentication before calling update_option() to save attacker-controlled OAuth tokens and app domain. This makes it possible for unauthenticated attackers to hijack the site's Infusionsoft connection by first triggering the OAuth flow to obtain the temporary password, then using that password to set arbitrary OAuth tokens and app domain via update_option(), effectively redirecting the plugin's API communication to an attacker-controlled server."}, {"lang": "es", "value": "El plugin FormLift for Infusionsoft Web Forms para WordPress es vulnerable a la falta de autorizaci\u00f3n en todas las versiones hasta la 7.5.21, inclusive. Esto se debe a la falta de comprobaciones de capacidad en los m\u00e9todos connect() y listen_for_tokens() de la clase FormLift_Infusionsoft_Manager, ambos enganchados a 'plugins_loaded' y que se ejecutan en cada carga de p\u00e1gina. La funci\u00f3n connect() genera una contrase\u00f1a de conexi\u00f3n OAuth y la filtra en el encabezado de redirecci\u00f3n Location sin verificar que el usuario solicitante est\u00e9 autenticado o autorizado. La funci\u00f3n listen_for_tokens() solo valida la contrase\u00f1a temporal, pero no realiza ninguna autenticaci\u00f3n de usuario antes de llamar a update_option() para guardar tokens OAuth y el dominio de la aplicaci\u00f3n controlados por el atacante. Esto hace posible que atacantes no autenticados secuestren la conexi\u00f3n de Infusionsoft del sitio al primero activar el flujo OAuth para obtener la contrase\u00f1a temporal, luego usando esa contrase\u00f1a para establecer tokens OAuth arbitrarios y el dominio de la aplicaci\u00f3n a trav\u00e9s de update_option(), redirigiendo efectivamente la comunicaci\u00f3n de la API del plugin a un servidor controlado por el atacante."}], "lastModified": "2026-03-30T13:26:50.827", "sourceIdentifier": "security@wordfence.com"}
