The backend/Login/load/ script in Shopware before 5.1.5 allows remote attackers to execute arbitrary code.

Shopware is an open source commerce platform based on Symfony Framework and Vue js. In a Twig environment without the Sandbox extension, it is possible to refer to PHP functions in twig filters like map, filter, sort. This allows a template to call any global PHP function and thus execute arbitrary code. The attacker must have access to a Twig environment in order to exploit this vulnerability. This problem has been fixed with 6.4.18.1 with an override of the specified filters until the integration of the Sandbox extension has been finished. Users are advised to upgrade. Users of major versions 6.1, 6.2, and 6.3 may also receive this fix via a plugin.

Impact The Shopware application API contains a search functionality which enables users to search through information stored within their Shopware instance. The searches performed by this function can be aggregated using the parameters in the “aggregations” object. The ‘name’ field in this “aggregations” object is vulnerable SQL-injection and can be exploited using time-based SQL-queries.

Patches Update to Shopware 6.5.7.4

Workarounds For older versions of 6.1, 6.2, 6.3 and 6.4 corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

Impact

Shopware has a new Twig Tag swsilentfeaturecall which silences deprecation messages while triggered in this tag. It accepts as parameter a string the feature flag name to silence, but this parameter is not escaped properly and allows execution of code.

Summary

An insufficient check on the filter types for unauthenticated customers allows access to orders of other customers. This is part of the deepLinkCode support on the store-api.order endpoint.

Details

Data Exposure

Depending on the order payload configuration, attackers may retrieve: - Customer names - Billing address - Shipping address - Email addresses - Ordered products - Order values - Order numbers - Order dates - Payment method information - Shipping method information - More customs, depending on the given associations in the request

Security Impact

This vulnerability allows: - Unauthorized access to foreign customer order data - Mass enumeration of recent orders - Potential scraping of customer personal information

Limitation

No limitation, but only orders from the past 30 days are checked for changeable means of payment (unrelated).

Impact

The code is present since ~2021. Likely every version since then is impacted for every store.

Summary

We identified and fixed a vulnerability in the Shopware app registration flow that could, under specific conditions, allow attackers to take over the communication channel between a shop and an app. By abusing app re‑registration, an attacker could redirect app traffic to an attacker‑controlled domain and potentially obtain API credentials intended for the legitimate shop. We have no evidence that this vulnerability has been exploited.

---

Affected Scope

- All apps (public and private) that use a registrationUrl in their app manifest and rely on the legacy HMAC‑based registration flow. - Both on‑premise and cloud installations are affected until updated to a fixed Shopware version or protected by the latest Shopware Security Plugin. - Shopware services and first‑party apps using the affected SDKs were reviewed and patched. The vulnerability does not affect core storefront or administration authentication; it is limited to the app system’s registration and re‑registration mechanism.

---

Impact

In a successful attack, an attacker who already knows certain app‑side secrets could: - Re‑register an existing app installation with a domain under their control. - Intercept App → Shop communication and cause data tampering (“data poisoning”). - Obtain API integration credentials of the shop with the permissions granted to the app. Shop owners and app manufacturers would typically observe this as “app malfunction” rather than an obvious security issue, which increases the need for hardening.

---

Root Cause

The legacy app registration flow used HMAC‑based authentication without sufficiently binding a shop installation to its original domain. During re‑registration, the shop-url could be updated without proving control over the previously registered shop or domain. This made targeted hijacking of app communication feasible if an attacker possessed the relevant app‑side secret.

---

Fix

We have hardened the app registration and re‑registration process: - Dual signature requirement: Re‑registration now requires both the app secret and the existing shop secret to be presented and validated. - Mandatory secret rotation: On successful re‑registration, a new shop secret is generated and verified; the previous secret is invalidated after a short grace period. - Stricter validation: Shopware only accepts updated shop URLs and secrets once the full confirmation flow has completed successfully. - Improved logging and monitoring: All re‑registrations are now logged with additional metadata to help detect abuse patterns. These changes are delivered via: - Updated Shopware core releases (6.6.x, 6.7.x), and - Updated versions of the Shopware Security Plugin for supported older versions, - Updated official SDKs (e.g. PHP and JavaScript app SDKs). ---

Required Action

For Merchants / Shop Operators

1. Update Shopware - Upgrade to the latest Shopware 6.6.x / 6.7.x release that includes this fix, or - Install/update the latest Shopware Security Plugin version providing the hotfix for your Shopware 6 installation. 2. Update apps - Ensure all installed apps are updated to the latest versions provided by their manufacturers. - If you suspect compromised keys or observe unexpected app behaviour, re‑install the affected app or trigger key rotation as documented by the app vendor.

For App Manufacturers / Partners

1. Update SDKs / implementations - Update to the latest Shopware app SDKs (PHP / JS) or apply the documented changes if you maintain a custom implementation of the registration flow. - Validate both shopware-app-signature and shopware-shop-signature for re‑registration requests. - Always generate and store a new shop secret on re‑registration and only switch to it after a successful confirmation. 2. Review your apps - Verify that your app does not blindly accept changed shop-url values without validating signatures. - Check any logic that exposes data or functionality based solely on HMAC signatures from shops and ensure it aligns with the hardened registration model. 3. Test your implementation - Use the updated tooling and guidance provided in your Shopware Account / partner channels to validate that your registration flow complies with the new requirements.

Versions prior to 6.4.3.1 contain an authenticated server-side request forgery vulnerability in file upload via URL. Version 6.4.3.1 contains a patch. As workarounds for older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin.

Shopware before 5.4.3 allows SQL Injection by remote authenticated users, aka SW-21404.

In createInstanceFromNamedArguments in Shopware through 5.6.x, a crafted web request can trigger a PHP object instantiation vulnerability, which can result in an arbitrary deserialization if the right class is instantiated. An attacker can leverage this deserialization to achieve remote code execution. NOTE: this issue is a bypass for a CVE-2017-18357 whitelist patch.

Impact We fixed with CVE-2023-22731 Twig filters to only be executed with allowed functions. It is possible to pass PHP Closures as string or an array and array crafted PHP Closures was not checked against allow list

Patches The problem has been fixed with 6.4.20.1 with an improved override.

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.

Shopware before 6.2.3 is vulnerable to a Server-Side Request Forgery (SSRF) in its "Mediabrowser upload by URL" feature. This allows an authenticated user to send HTTP, HTTPS, FTP, and SFTP requests on behalf of the Shopware platform server.

Impact The context variable is injected into almost any Twig Template and allows to access to current language, currency information. The context object allows also to switch for a short time the scope of the Context as a helper with a callable function.

Example call from PHP:

php $context->scope(Context::SYSTEMSCOPE, static function (Context $context) use ($mediaService, $media, &$fileBlob): void { $fileBlob = $mediaService->loadFile($media->getId(), $context); });

This function can be called also from Twig and as the second parameter allows any callable, it's possible to call from Twig any statically callable PHP function/method.

It's not possible as customer to provide any Twig code, the attacker would require access to Administration to exploit it using Mail templates or using App Scripts.

Patches Update to Shopware 6.6.5.1 or 6.5.8.13

Workarounds For older versions of 6.1, 6.2, 6.3 and 6.4 corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

Shopware is an open headless commerce platform. The implemented Flow Builder functionality in the Shopware application does not adequately validate the URL used when creating the “call webhook” action. This enables malicious users to perform web requests to internal hosts. This issue has been fixed in the Commercial Plugin release 6.5.7.4 or with the Security Plugin. For installations with Shopware 6.4 the Security plugin is recommended to be installed and up to date. For older versions of 6.4 and 6.5 corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

Shopware is an open source e-commerce software platform. In affected versions shopware would not invalidate a user session in the event of a password change. With version 5.7.7 the session validation was adjusted, so that sessions created prior to the latest password change of a customer account can't be used to login with said account. This also means, that upon a password change, all existing sessions for a given customer account are automatically considered invalid. There is no workaround for this issue.

Shopware is an open commerce platform based on Symfony Framework and Vue. Permissions set to sales channel context by admin-api are still usable within normal user session. Users are advised to update to the current version 6.4.10.1. For older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin. There are no known workarounds for this issue.

Shopware is an open source eCommerce platform. Versions prior to 6.4.3.1 contain a Cross-Site Scripting vulnerability via SVG media files. Version 6.4.3.1 contains a patch. As workarounds for older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin.

Impact

The Symfony Session Handler, pop's the Session Cookie and assign it to the Response. Since Shopware 6.5.8.0 the 404 pages, are cached, to improve the performance of 404 pages. So the cached Response, contains a Session Cookie when the Browser accessing the 404 page, has no cookies yet. The Symfony Session Handler is in use, when no explicit Session configuration has been done. When Redis is in use for Sessions using the PHP Redis extension, this exploiting code is not used.

Patches Update to Shopware version 6.5.8.7

Workarounds Using Redis for Sessions, as this does not trigger the exploit code. Example configuration for Redis

ini php.ini session.savehandler = redis session.savepath = "tcp://127.0.0.1:6379"

Consequences

As an guest browser session has been cached on a 404 page, every missing image or directly reaching a 404 page will logout the customer or clear his cart.

Impact

It's possible to pass long passwords that leads to Denial Of Service via forms in Storefront forms or Store-API.

Patches Update to Shopware 6.6.10.3 or 6.5.8.17

Workarounds For older versions of 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

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.

Shopware is an open source eCommerce platform. In versions prior to 6.4.1.1 private files publicly accessible with Cloud Storage providers when the hashed URL is known. Users are recommend to first change their configuration to set the correct visibility according to the documentation. The visibility must be at the same level as type. When the Storage is saved on Amazon AWS we recommending disabling public access to the bucket containing the private files: https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-control-block-public-access.html. Otherwise, update to Shopware 6.4.1.1 or install or update the Security plugin (https://store.shopware.com/en/detail/index/sArticle/518463/number/Swag136939272659) and run the command ./bin/console s3:set-visibility to correct your cloud file visibilities.

In Shopware 6 before 6.2.3, the database password is leaked to an unauthenticated user when a DriverException occurs and verbose error handling is enabled. This vulnerability does not affect the shopware 5 release branch (shopware/shopware on packagist).

Shopware is an open commerce platform based on the Symfony php Framework and the Vue javascript framework. In versions prior to 6.4.8.2 it is possible to modify customers and to create orders without App Permission. This issue is a result of improper api route checking. Users are advised to upgrade to version 6.4.8.2. There are no known workarounds.

Shopware is an open source e-commerce software platform. Starting with version 5.0.4 and before version 5.7.9, multiple tokens for password reset can be requested. All tokens can be used to change the password. This makes it possible for an attacker to take over the victim's account if they somehow gain access to the victims email account and find an unused password reset token in the emails. This issue is fixed in version 5.7.9.

Shopware is an open source e-commerce software platform. Versions prior to 5.7.9 are vulnerable to malfunction of cross-site request forgery (CSRF) token validation. Under certain circumstances, the CSRF tokens were not generated anew and not validated correctly. This issue is fixed in version 5.7.9. Users of older versions may attempt to mitigate the vulnerability by using the Shopware security plugin.

Shopware is an open source commerce platform based on Symfony Framework and Vue js. The newsletter double opt-in validation was not checked properly, and it was possible to skip the complete double opt in process. As a result operators may have inconsistencies in their newsletter systems. This problem has been fixed with version 6.4.18.1. Users are advised to upgrade. Users unable to upgrade may find security measures are available via a plugin for major versions 6.1, 6.2, and 6.3. Users may also disable newsletter registration completely.
