Descriptions

Django before 1.11.27, 2.x before 2.2.9, and 3.x before 3.0.1 allows account takeover. A suitably crafted email address (that is equal to an existing user's email address after case transformation of Unicode characters) would allow an attacker to be sent a password reset token for the matched user account. (One mitigation in the new releases is to send password reset tokens only to the registered user email address.)

Django versiones anteriores a 1.11.27, versiones 2.x anteriores a 2.2.9 y versiones 3.x anteriores a 3.0.1, permite tomar el control de la cuenta. Una dirección de correo electrónico diseñada adecuadamente (que es igual a la dirección de correo electrónico de un usuario existente después de la transformación de mayúsculas y minúsculas de los caracteres Unicode) permitiría a un atacante enviarle un token de restablecimiento de contraseña para la cuenta de usuario coincidente. (Una mitigación en las nuevas versiones es enviar tokens de restablecimiento de contraseña solo a la dirección de correo electrónico del usuario registrado).

Simon Charette reported that the password reset functionality in Django, a high-level Python web development framework, uses a Unicode case-insensitive query to retrieve accounts matching the email address requesting the password reset. An attacker can take advantage of this flaw to potentially retrieve password reset tokens and hijack accounts.
