Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Shopware is an open source e-commerce software platform. Prior to 6.6.10.3 or 6.5.8.17, the default settings for double-opt-in allow for mass unsolicited newsletter sign-ups without confirmation. Default settings are Newsletter: Double Opt-in set to active, Newsletter: Double opt-in for registered customers set to disabled, and Log-in & sign-up: Double opt-in on sign-up set to disabled. With these settings, anyone can register an account on the shop using any e-mail-address and then check the check-box in the account page to sign up for the newsletter. The recipient will receive two mails confirming registering and signing up for the newsletter, no confirmation link needed to be clicked for either. In the backend the recipient is set to “instantly active”. This vulnerability is fixed in 6.6.10.3 or 6.5.8.17.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Shopware prior to 6.6.10.3 or 6.5.8.17 has insecure default double-opt-in settings for newsletter subscriptions. When Newsletter: Double Opt-in is active but 'Double opt-in for registered customers' and 'Double opt-in on sign-up' are disabled, registered users can subscribe to newsletters without clicking a confirmation link, resulting in instantly active subscriptions.

MitigationUpdate Shopware to version 6.6.10.3 or 6.5.8.17, or explicitly enable 'Double opt-in for registered customers' and 'Double opt-in on sign-up' settings in the Shopware admin configuration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Shopware version
    Locate the Shopware installation and identify the exact version number (typically in a composer.json file, changelog, or admin panel under Settings > Basic Information > Version)
    Affected if The installed version is less than 6.5.8.17, or between 6.6.0.0 and 6.6.10.2, or exactly 6.7.0.0
  2. Verify Newsletter Double Opt-in is enabled
    Check the Shopware admin configuration under Settings > Newsletter > Newsletter registration, or inspect the system_config database table for the config key 'core.newsletter.doubleOptIn' set to true
    Affected if Newsletter Double Opt-in is active (enabled)
  3. Check if Double opt-in for registered customers is disabled
    Inspect the Shopware admin configuration under Settings > Newsletter > Newsletter registration, or query the system_config database table for the config key 'core.newsletter.doubleOptInRegistered' and verify it is set to false or is absent
    Affected if This setting is disabled or not explicitly set to true for registered customers
  4. Check if Double opt-in on sign-up is disabled
    Inspect the Shopware admin configuration under Settings > Newsletter > Newsletter registration, or query the system_config database table for the config key 'core.newsletter.doubleOptInOnSignup' and verify it is set to false or is absent
    Affected if This setting is disabled or not explicitly set to true on sign-up

You are affected if your Shopware version falls within the vulnerable ranges AND Newsletter Double Opt-in is enabled while BOTH 'Double opt-in for registered customers' and 'Double opt-in on sign-up' are disabled, allowing instant newsletter subscriptions without email confirmation for registered users.
