Online shopping has the convenience of collecting items and dispensing personal judgement on the things you like and the things you don’t. All this without having the effort of hauling those things around a labyrinth of smells and sounds! And with the Abandoned Cart plugin for WordPress sites, the site administrator can hold on to your cart in case you have a desire to pick up where you left off if a sudden pressing matter arises, or you simply lose interest for the time being. But WordFence security researchers have noticed a flaw in the execution of the Abandoned Cart plugin which enables a complete site takeover along with laying a secondary backdoor to regain access in case of discovery.
A patch for this vulnerability was released, which uses WordPress’ own data sanitizer to exclude names beginning with “<“ and any account with “woouser” in the email. While this prevents the initial attack from creating adversary controlled accounts, it doesn't address the code injection in the deactivated plugins.
