Edit on GitHub

The following information pertains to security-related issues that were discovered and resolved. Issues are listed by description and affected modules.

If you need any additional support with this content, please contact If you found a new security vulnerability, please inform us via

OMS and StateMachine Module Vulnerability

Both OMS and standalone StateMachine module were exposing their State Machine triggers directly via URL in Zed backend. Those actions could be invoked via GET which violated basic HTTP specs and security audits, thus allowing “hidden” or accidental links, faced images etc.

We have solved this issue by changing the type of HTTP request for OMS triggering button from GET to POST.

Affected modules:

  • Oms (10.1.0)
  • Sales (10.2.0)
  • SalesReclamationGui (1.2.0)

How to get the fix:

Just update the modules with

composer update spryker/oms spryker/sales spryker/sales-reclamation-gui

Incorrect Usage of Zed Request Configuration Constants

This issue is not a security vulnerability itself but may prevent mistakes. Currently, there is an unused and deprecated factory method \Spryker\Shared\ZedRequest\Provider\AbstractZedClientProvider::createZedClient(). In this method, when instance of \Spryker\Client\ZedRequest\Client\HttpClient class is created, the string value is passed from Config::get(ZedRequestConstants::TRANSFER_PASSWORD) as the third argument $isAuthenticationEnabled, which is incorrect and misleading. Thus, unexpected behavior might occur when using that factory method on a project level. Since those constants are not used in the default config, the solution, for now, was to deprecate ZedRequestConstants::TRANSFER_PASSWORD and ZedRequestConstants::TRANSFER_USERNAME to remove them later in a major release.

Affected module:

  • ZedRequest (3.8.1)

How to get the fix:

  • Update the modules with
    composer update spryker/product-attribute-gui
  • Remove the lines where $config[ZedRequestConstants::TRANSFER_USERNAME] and $config[ZedRequestConstants::TRANSFER_USERNAME] are used inside the config_defaul.php file. Also, do the same for config_defaul_{env}_{store}.php if needed.

Missing “Host” Header Validation (Server-side Injection Vulnerability)

Previously, application functionality was trusting the user-supplied Host header. Supplying a malicious Host header for example with a password reset request might lead to a poisoned password reset link and is considered vulnerable for the classic server-side injection. Depending on the configuration of the server and any caching proxies in between, it might also be possible to use this technique for cache poisoning attacks. To prevent this, Yves trusted hosts list $config[ApplicationConstants::YVES_TRUSTED_HOSTS] has been utilized, configured and set in the project config files config_default_AT.php, config_default_DE.php, config_default_US.php.

Affected module:

  • non-split only

How to get the fix: Set a correct value for $config[ApplicationConstants::YVES_TRUSTED_HOSTS] in config files on the project level.

Missing Referrer-Policy and Feature-Policy Headers Defaults

Initially, neither Referrer-Policy nor Feature-Policy headers were used in the application. In this release, we have fixed the missing security headers Referrer-Policy and Feature-Policy by adjusting HeadersSecurityServiceProvider::onKernelResponse() with added Referrer-Policy: same-origin and Feature-Policy:.

Affected module:

  • Application (3.18.0)

How to get the fix:

  1. Update the modules with
composer update spryker/application
  1. Add new \Spryker\Yves\Application\Communication\Plugin\EventDispatcher\HeadersSecurityEventDispatcherPlugin() inside the EventDispatcherDependencyProvider::getEventDispatcherPlugins() plugins stack for the Yves layer.
  2. Add new \Spryker\Zed\Application\Communication\Plugin\EventDispatcher\HeadersSecurityEventDispatcherPlugin() inside the EventDispatcherDependencyProvider::getEventDispatcherPlugins() plugins stack for the Zed layer.
  3. Un-register Spryker\Shared\Application\ServiceProvider\HeadersSecurityServiceProvider by removing line $this->application->register(new HeadersSecurityServiceProvider()); from the \Pyz\Yves\ShopApplication\YvesBootstrap::registerServiceProviders() method.

Disabled CSFR Validation in ManualOrderEntryGui

Previously, all form data providers in ManualOrderEntryGui module had csrf_protection equal to false. This release provides a fix for csrf-protection which had been disabled on the manual order entry in the back-office.

Affected module: ManualOrderEntryGui (0.7.1)

How to get the fix: Update the modules with

composer update spryker/manual-order-entry-gui

Fixed Various JS Vulnerabilities

  • Updated plotly.js dependency to the newest version 1.48.3
  • Security fix: safeLoad() can hang when arrays with nested refs are used as a key. Now an exception is thrown for the nested arrays. Fix possible code execution in (already unsafe) .load().
  • Updated dot dependency to the newest version 1.1.2.
  • Updated jquery dependency to the newest version 3.4.1.j
  • Query 3.4.0 includes a fix for some unintended behavior when using jQuery.extend(true, {}, ...). If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype.
  • Updated bootstrap-sass dependency to the newest version 3.4.1.
  • Fixed an XSS vulnerability (CVE-2019-8331) in our tooltip and popover plugins by implementing a new HTML sanitize.

Affected modules:

  • Chart (1.2.0)
  • Discount (9.1.0)
  • ProductRelation (2.3.0)
  • Gui (3.23.0)

How to get the fix:

  1. Update the modules with
composer update spryker/chart spryker/discount spryker/product-relation spryker/gui
  1. Run
console frontend:project:install-dependencies
