CVE-2024-8796

Under the default configuration, Devise-Two-Factor versions >= 2.2.0 & < 6.0.0 generate TOTP shared secrets that are 120 bits instead of the 128-bit minimum defined by RFC 4226. Using a shared secret shorter than the minimum to generate a multi-factor authentication code could make it easier for an attacker to guess the shared secret and generate valid TOTP codes.

Summary		(es) Con la configuración predeterminada, las versiones de Devise-Two-Factor >= 2.2.0 y < 6.0.0 generan secretos compartidos TOTP de 120 bits en lugar del mínimo de 128 bits definido por RFC 4226. El uso de un secreto compartido más corto que el mínimo para generar un código de autenticación multifactor podría facilitar que un atacante adivine el secreto compartido y genere códigos TOTP válidos.
