Shopware has Improper Input Validation issue in newsletter subscription
### Impact The newsletter double opt-in validation was not checked properly, and it was possible to skip the complete double opt in process. ### Patches The problem has been fixed with 6.4.18.1 ### Workarounds For older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version. Or disable the newsletter registration completely. ### References https://docs.shopware.com/en/shopware-6-en/security-updates/security-update-01-2023?category=security-updates
