Descriptions

Mattermost versions 9.5.x <= 9.5.3, 9.7.x <= 9.7.1, 9.6.x <= 9.6.1 and 8.1.x <= 8.1.12 fail to check if the email signup configuration option is enabled when a user requests to switch from SAML to Email. This allows the user to switch their authentication mail from SAML to email and possibly edit personal details that were otherwise non-editable and provided by the SAML provider.

Las versiones de Mattermost 9.5.x &lt;= 9.5.3, 9.7.x &lt;= 9.7.1, 9.6.x &lt;= 9.6.1 y 8.1.x &lt;= 8.1.12 no verifican si la opción de configuración de registro de correo electrónico está habilitada cuando un el usuario solicita cambiar de SAML a correo electrónico. Esto permite al usuario cambiar su correo de autenticación de SAML a correo electrónico y posiblemente editar datos personales que de otro modo no serían editables y proporcionados por el proveedor de SAML.
