GHSA-6w82-v552-wjw2: Shopware Storefront Reflected XSS in Storefront Login Page

December 9, 2025

A request parameter from the URL of the login page is directly rendered within the Twig template of the Storefront login page without further processing or input validation. This allows direct code injection into the template via the URL parameter. An attacker can create malicious links that could be used in a phishing attack. The parameter waitTime lacks proper input validation.

The attack can be tested with the following URL pattern:

/account/login?loginError=1&waitTime=<a%20href%3D"https%3A%2F%2Fde.wikipedia.org%2Fwiki%2FPhishing">Here<%2Fa>

The same applies to the errorSnippet parameter:
