Description
A flaw was found in Keycloak. An authenticated user can bypass configured WebAuthn policies during credential registration by manipulating client-side JavaScript. This occurs because the server-side processAction() fails to validate that the newly created credential's parameters, such as public key algorithms, match the realm's configured WebAuthn policies. This could lead to the creation of credentials that do not adhere to administrative security requirements, potentially weakening the overall security posture of the system by allowing non-compliant authentication methods.

Title: Red Hat Build de Keycloak, Description: Se encontró un fallo en Keycloak. Un usuario autenticado puede eludir las políticas WebAuthn configuradas durante el registro de credenciales manipulando JavaScript del lado del cliente. Esto ocurre porque el processAction() del lado del servidor no valida que los parámetros de la credencial recién creada, como los algoritmos de clave pública, coincidan con las políticas WebAuthn configuradas del reino. Esto podría llevar a la creación de credenciales que no cumplen con los requisitos de seguridad administrativos, debilitando potencialmente la postura de seguridad general del sistema al permitir métodos de autenticación no conformes.
