As a result operators may have inconsistencies in their newsletter systems. This problem has been fixed with version 6.4.18.1. Users are advised to upgrade. Users unable to upgrade may find security measures are available via a plugin for major versions 6.1, 6.2, and 6.3. Users may also disable newsletter registration completely.
