Descriptions

After user deletion in MongoDB Server the improper invalidation of authorization sessions allows an authenticated user's session to persist and become conflated with new accounts, if those accounts reuse the names of deleted ones. This issue affects MongoDB Server v4.0 versions prior to 4.0.9; MongoDB Server v3.6 versions prior to 3.6.13 and MongoDB Server v3.4 versions prior to 3.4.22.

Workaround:
After deleting one or more users, restart any nodes which may have had active user authorization sessions.

Refrain from creating user accounts with the same name as previously deleted accounts.

Después de la eliminación del usuario en MongoDB Server, la incomprobación incorrecta de las sesiones de autorización permite que la sesión de usuario autenticada persista y venga combinada con cuentas nuevas, si esas cuentas reutilizan los nombres de las eliminadas. Este problema afecta a: MongoDB Inc. MongoDB Server versiones v4.0 anteriores a 4.0.9; versiones v3.6 anteriores a 3.6.13; versiones v3.4 anteriores a 3.4.22.
