Shopware guest session is shared between customers

Impact

Guest sessions are shared between customers when HTTP cache is enabled. Setups with Varnish are not affected by this issue

Patches

We recommend updating to the current version 6.4.8.2. You can get the update to 6.4.8.2 regularly via the Auto-Updater or directly via the download overview.

Workarounds

Security Plugin

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.

Disable HTTP Cache

Disabling HTTP Cache is also a valid workaround
