The Conditional Authentication script is vulnerable due to improper enforcement of required authentication steps, allowing attackers to bypass intermediate challenges in specific multi-step configurations. Successful exploitation can lead to unauthorized access to user accounts, particularly affecting applications that utilize certain secondary authenticators and specific callback configurations. Organizations using adaptive authentication mechanisms should prioritize addressing this critical vulnerability to safeguard user accounts from potential breaches.

Original NVD Description

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.
