In October 2017, a big vulnerability with the WPA2 Wi-Fi standard was discovered. Referred to as KRACK, this is a vulnerability that essentially makes open season on all your personal data when connected to a Wi-Fi network using WPA2.
You can find all of the information about KRACK in Jerry's guide here, but when talking about newer Android devices specifically, it's important to note the following:
On phones running Android 6.0 Marshmallow and newer, the KRACK vulnerability can force the Wi-Fi connection to create an absurdly easy-to-crack encryption key of 00:00:00:00:00. With something so simple, it's easy for an outsider to read all of the traffic coming to and from a client, like a smartphone or laptop.
Attackers can't necessarily use KRACK to steal your bank account information or passwords, but it's still something that you want to protect yourself from as much as possible. Both Wi-Fi routers and devices connected to them need to receive a software update in order to be free form potential attacks, but at least in the case of Android phones and tablets, these are the gadgets that are safe to use.
