Vulnerabilidad · Publicado 06/08/2026
Un fallo en los scripts de Autenticación Condicional (Adaptive Authentication) permite a atacantes eludir desafíos de autenticación intermedios en configuraciones de múltiples pasos. La vulnerabilidad afecta sistemas de control de acceso empresariales en toda Latinoamérica, poniendo en riesgo aplicaciones críticas que dependen de autenticación multifactor. Con puntuación CVSS 9.4, este vector compromete la integridad de flujos de autenticación en plataformas de identidad y control de acceso.
The Conditional Authentication (Adaptive Authentication) script does not correctly enforce the completion of all required authentication steps when a specific multi-step pattern involving certain authenticators is configured. This allows an attacker to bypass intermediate authentication challenges by exploiting how the script handles callbacks and re-execution of authentication steps. Successful exploitation allows a malicious actor to gain unauthorized access to a targeted user account. This vulnerability can only be exploited when all of the following conditions are met: the application login flow contains a specific secondary authenticator, the Conditional Authentication script is configured with particular event callbacks and re-executes an authentication step, the targeted user has one of the impacted authenticators enrolled, and the attacker successfully completes any preceding authentication steps.
