Securing Your Shopware Store: Great Steps You Can Take Today for Better Security!

The PHP security vulnerabilities surrounding PHP2Shell demonstrated in October 2026 just how quickly even a smoothly running online store can find itself under immense pressure to act. These vulnerabilities affected the technical foundation of many websites and online shops. On October 21, the PHP project released the corresponding security updates. Background: PHP Foundation

For you as a store owner, however, the most important question isn't just what happened during this specific incident. Rather, it's: What can I do to keep my store better protected in the future and enable our team to respond even faster when the next security issue arises?

The good news is that you don't need to become a cybersecurity expert! The key factors are maintaining a clear overview of your technical health, setting well-defined responsibilities, and ensuring regular maintenance. In this article, we’ll show you seven concrete steps to take and explain how Frosh Tools and our security package for Shopware 6 can support you along the way.

If your store's PHP2Shell patch status is still unconfirmed: Please have your hosting provider or technical service team check it right away! The preventive recommendations below are no substitute for resolving an already known vulnerability. You can find up-to-date advisories at CERT-EU.

Security doesn't start with the next attack

As long as orders keep rolling in and the checkout runs smoothly, an online shop often appears technically sound on the surface. However, it’s virtually impossible from the outside to tell whether critical security updates are missing, a PHP version has reached its end of life, or former team members still hold administrator access.

That's why security should naturally be just as much a part of day-to-day operations as managing products, prices, and payment methods.

It all boils down to three core goals:

• Reduce attack surfaces: Avoid outdated software, unnecessary user access, and risky configurations.

• Spot issues early: Keep a close eye on version statuses and suspicious activities.

• Stay ready to act: Establish clear responsibilities, solid backups, and effective emergency workflows.

No single plugin can cover everything on its own. Your measures need to work seamlessly together as a team.

1. Get a clear overview of your store

The first step is a simple audit of your setup. You should know which Shopware version is running, which plugins are installed, and which PHP version powers your store.

Just as important: Who is taking care of which component?

Don't forget staging environments, subdomains, and legacy installations! Make sure they aren't quietly lingering online while only your live store receives attention.

Frosh Tools makes version checks a breeze

For Shopware 6, the free extension Tools by Friends of Shopware (widely known as Frosh Tools) is a fantastic helper.

Its system status checks your PHP version among other key parameters. It also alerts you to outdated Shopware versions. This allows you to spot update requirements directly in your administration panel and address them proactively with your technical partner.

Remember that Frosh Tools itself should always be kept up-to-date and compatible with your Shopware release. The findings depend on the built-in checks. A green status isn't a 100% guarantee that all vulnerabilities are ruled out; for example, backported hosting patches must be evaluated individually.

Your first step: Check your system status with your technical service provider and turn open notifications into actionable tasks.

2. Turn updates into a routine process

“We’ll update when something breaks” is simply not a viable security strategy. Security vulnerabilities can exist even while your shop continues to process customer orders without a hitch.

Define clear answers to these questions:

• Who monitors relevant security announcements?

• Who evaluates whether your store is affected?

• Who is authorized to approve and deploy updates?

• Which functions are verified afterwards?

• How are potential issues handled?

Automatic updates require thorough verification

Automating plugin updates can be a fantastic way to apply fixes swiftly. Which extensions are set to update automatically should always be tailored to your specific store setup.

After an update, just glancing at the homepage isn’t enough. Make sure to test your core user journeys: customer login, product selection, shopping cart, checkout, and order completion. A documented checklist provides the perfect, reliable foundation for this.

Keep the Shopware Security Plugin up-to-date

However, it does not permanently replace routine store maintenance or security updates for PHP and the underlying server.

Your next step: Establish a clear update process with an expedited path for critical security alerts.

3. Check PHP independently from Shopware

PHP is the runtime environment powering core parts of your online store. A fully updated Shopware store can still be running on an outdated or unpatched version of PHP.

This highlights one of the major takeaways from PHP2Shell: security issues can exist below the application layer. When that happens, updating Shopware or plugins won't resolve them.

Make sure to check regularly:

• Which PHP version is the web server actually running?

• Is this version branch still receiving security updates?

• Are all relevant patches applied?

• Do background processes happen to run on a different PHP version?

• Is a version upgrade compatible with your Shopware release and active extensions?

With managed hosting and distribution packages, security fixes might be backported to older version numbers. The visible version string alone isn't always conclusive; what matters is the confirmed package and patch status. Background: PHP Security Announcement

Plan necessary version upgrades well in advance. If an older extension is holding back an upgrade, make sure to resolve that dependency proactively.

Your next step: Request confirmation of your active PHP patch level and clarify who is responsible for future updates.

4. Secure access to your administration panel

Not every attack relies on a technical software flaw. Compromised or shared credentials pose just as significant a risk. That's why securing user accounts is fundamental to keeping your business safe.

Here are the most effective best practices:

• Personal user accounts instead of shared administrator logins,

• Granting only the permissions strictly needed for each specific role,

• Unique, strong passwords,

• Two-factor authentication (2FA),

• Promptly deactivating accounts that are no longer needed.

With two-factor authentication, an additional verification step—such as a time-based code from an authenticator app—is required alongside the password. This makes unauthorized access using stolen credentials vastly more difficult.

A custom admin URL can also help deter automated bots scanning for default paths. However, it is an extra layer, not a replacement for strong authentication and access control.

Important: These measures safeguard admin access. They do not fix PHP vulnerabilities that can be exploited without logging in.

Your next step: Review your user list and enable 2FA for all administrative accounts.

5. Track unusual activity and backend changes

If a new administrator is created or a critical configuration setting is modified, you should always be able to trace when it happened and which user account performed the action.

Two types of logs are particularly valuable here:

• Login logs: Successful logins alongside failed sign-in attempts.

• Audit logs: Documented modifications across supported administration areas.

This data makes investigating anomalies much easier. However, logs are only as good as the team reviewing them—be sure it's clear who analyzes them when needed. Logging alone does not stop an attack or automatically detect every incident.

Access permissions and data retention periods for logs should also be clearly defined.

Your next step: Clarify what activity is already being logged and designate who investigates unusual events.

6. Ensure your store can be restored smoothly

Having a backup is great. Having complete certainty that it actually works when needed is even better!

Double-check these points with your hosting partner:

• Are database, files, and critical configuration settings backed up?

• Are backups securely stored separate from the live server environment?

• How current would a restored system state be?

• How long would a full restore realistically take?

• Has the restore process actually been tested?

For online retailers, the potential loss of recent customer orders is a vital consideration. Your backup strategy should match your business needs perfectly.

Keep in mind: a backup is never a replacement for a security patch. Following a restoration, any underlying vulnerability must be resolved before bringing the store back online. In the event of an attack, you must also ensure backups haven't already been tampered with.

Your next step: Schedule a backup recovery test and document the results.

7. Know who takes action before an emergency happens

When a critical security alert lands, you don't want to spend precious time figuring out who is responsible for what.

A concise incident response plan should clarify:

• Who is the primary contact at your host and your agency partner?

• Who determines if your system is affected?

• Who has the authority to approve emergency measures or temporarily take the store offline?

• Who validates store functionality once fixes are deployed?

• Who handles internal communications and informs customers if necessary?

Additional protective tools—like a Web Application Firewall, segmented environments, or restricted server permissions—can provide fantastic benefits. Which of these are right for you will depend on your specific hosting setup. They complement regular updates, but can never replace them.

If there are concrete signs of an intrusion, simply deploying a patch after the fact is not enough. Any compromised system components must be carefully audited and remediated. Be sure to preserve forensic evidence and involve cybersecurity specialists.

Your next step: Document your key contacts, responsibilities, and sign-off workflows in writing.

Your checklist: How prepared is your online store?

You don’t have to handle all technical implementations yourself, but you should definitely be able to answer these key questions with confidence:

• We know our current Shopware, plugin, and PHP versions.

• Recommendations from Frosh Tools are regularly checked and addressed.

• Clear owners are assigned for updates and critical security bulletins.

• Key storefront functions are tested immediately after updates.

• Admin accounts are personalized and secured with multi-factor authentication.

• Logins and critical administrative changes are reliably logged.

• Backups are isolated and recovery procedures have been verified.

• We have clear points of contact and response protocols for security incidents.

Any box you can’t check off right now points to an area where prompt action is recommended!
