CVE-2021-32710Network attack vector

Customer session hijacking via incomplete logout invalidation

Published Jun 24, 2021 · Updated Aug 3, 2024

Session invalidation failure in the storefront logout flow in Shopware Platform before 6.3.5.2 allows remote attackers to hijack customer sessions. AuthController invalidates the HTTP session only when invalidateSessionOnLogOut is enabled, while StorefrontSubscriber reuses the sales-channel token instead of generating a fresh token. An attacker must possess a customer's existing session token; reuse after that customer logs out preserves access to the customer's storefront session.
