CVE-2026-64964

ATutor generates predictable email confirmation tokens due to the use of insufficiently random values in the account confirmation functionality. Due to the use of predictable values related to user registration, an attacker who knows or can predict these values can guess valid account activation tokens. This allows an attacker to activate an unconfirmed account without access to the victim's email inbox. Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

Summary		(es) ATutor genera tokens de confirmación de correo electrónico predecibles debido al uso de valores insuficientemente aleatorios en la funcionalidad de confirmación de cuenta. Debido al uso de valores predecibles relacionados con el registro de usuario, un atacante que conoce o puede predecir estos valores puede adivinar tokens de activación de cuenta válidos. Esto permite a un atacante activar una cuenta no confirmada sin acceso a la bandeja de entrada de correo electrónico de la víctima. El producto ya no recibe soporte activamente y las vulnerabilidades no han sido corregidas. Solo la versión 2.2.4 fue probada y confirmada como vulnerable, otras versiones no fueron probadas pero también podrían ser vulnerables.
