I run a huge store with 1k unique users per day and there been 2 incidents that bothers me. When user registers he logs in to different account.
For example I register as John Smith and will be logged as existing user Mr. Anderson, who really exists in system as registered user and can access to all data, order history etc..
Did anyone faced that problem? Becouse this is serious security issue. I cannot reproduce that problem and that scares me even more.
I’m runing Magento 184.108.40.206 version
