Shopware is an open source eCommerce platform. Versions prior to 6.3.5.1 may leak of information via Store-API. The vulnerability could only be fixed by changing the API system, which involves a non-backward-compatible change. Only consumers of the Store-API should be affected by this change. We recommend to update to the current version 6.3.5.1. You can get the update to 6.3.5.1 regularly via the Auto-Updater or directly via the download overview. https://www.shopware.com/en/download/#shopware-6 The vulnerability could only be fixed by changing the API system, which involves a non-backward-compatible change. Only consumers of the Store-API should be affected by this change. Please check your plugins if you have it in use. Detailed technical information can be found in the upgrade information. https://github.com/shopware/platform/blob/v6.3.5.1/UPGRADE-6.3.md#6351 ### Workarounds For older versions of 6.1 and 6.2, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version. https://store.shopware.com/en/detail/index/sArticle/518463/number/Swag136939272659 ### For more information https://docs.shopware.com/en/shopware-6-en/security-updates/security-update-02-2021

A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.
CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.
A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.
Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.
Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.
SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
