I have Magento Enterprise Edition 184.108.40.206 installed. So do i need to apply security patch SUPEE-10570? Is it compatible with Magento Enterprise Edition 220.127.116.11?
According to their security patch notes here you need to apply that patch. I'll just rewrite only the important parts:
Patches and upgrades are available for the following Magento versions:
Magento Commerce 18.104.22.168-22.214.171.124: SUPEE-10570 or upgrade to Magento Commerce 126.96.36.199
Magento Open Source 188.8.131.52-184.108.40.206: SUPEE-10570 or upgrade to Magento Open Source 220.127.116.11
It also says that the security flaw affects
Magento Commerce prior to 18.104.22.168 which means it affects version
Magento Commerce is
Magento Open Source is
Magento Community Edition.
