What is CVE-2025-32378?

The Shopware e-commerce platform, prior to versions 6.6.10.3 and 6.5.8.17, is affected by a vulnerability that allows for mass unsolicited newsletter sign-ups. This occurs due to default configurations that enable the double opt-in feature for newsletters but leave certain options disabled, such as the requirement for email confirmation for newsletter subscriptions. As a result, users can register accounts with any email address and subscribe to newsletters without needing to verify their email. This flaw can lead to misuse for spam and other malicious activities. Users are advised to update to the patched versions to secure their platforms.
