CVE-2026-56450
AIL Framework - Missing Rate Limiting Enables Brute-Force Attacks Against Two-Factor Authentication Codes
Description
AIL did not restrict repeated failed attempts to verify a two-factor authentication (OTP) code. An attacker who had reached the 2FA verification step, such as after successfully completing the password-authentication stage, could submit an unlimited number of OTP guesses. This could enable brute-force guessing of a valid code and bypass the intended second authentication factor, resulting in unauthorized account access. The patch introduces per-user failed-OTP tracking, blocks verification after 30 failed attempts for one hour, clears the counter after a successful OTP verification, and provides administrator recovery actions to purge affected lockouts.

Action Type Old Value New Value Added Translation Title: ail framework de ail project, Description: AIL no restringía los intentos fallidos repetidos para verificar un código de autenticación de dos factores (OTP). Un atacante que había alcanzado el paso de verificación 2FA, como después de completar exitosamente la etapa de autenticación de contraseña, podía enviar un número ilimitado de intentos de OTP. Esto podría permitir el adivinado por fuerza bruta de un código válido y eludir el segundo factor de autenticación previsto, lo que resultaría en acceso no autorizado a la cuenta. El parche introduce el seguimiento de OTP fallidos por usuario, bloquea la verificación después de 30 intentos fallidos durante una hora, borra el contador después de una verificación OTP exitosa y proporciona acciones de recuperación del administrador para purgar los bloqueos afectados. -
