Descriptions

Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.x <= 9.10.0 and 9.8.x <= 9.8.2 fail to ensure that remote/synthetic users cannot create sessions or reset passwords, which allows the munged email addresses, created by shared channels, to be used to receive email notifications and to reset passwords, when they are valid, functional emails.

Las versiones de Mattermost 9.9.x &lt;= 9.9.1, 9.5.x &lt;= 9.5.7, 9.10.x &lt;= 9.10.0 y 9.8.x &lt;= 9.8.2 no garantizan que los usuarios remotos/sintéticos no puedan crear sesiones ni restablecer contraseñas, que permite que las direcciones de correo electrónico eliminadas, creadas por canales compartidos, se utilicen para recibir notificaciones por correo electrónico y restablecer contraseñas, cuando sean correos electrónicos válidos y funcionales.
