Men in the Middle(MitM) attacks

Cross Site Scripting(XSS) attacks
Cross-site scripting (also known as XSS) is a web security vulnerability that allows an attacker to compromise the interactions that users have with a vulnerable application. When the malicious code executes inside a victim’s browser, the attacker can fully compromise their interaction with the application.
An eavesdropping attack, also known as a sniffing or snooping attack, is a theft of information as it is transmitted over a network by a computer, smartphone, or another connected device. The attack takes advantage of unsecured network communications to access data as it is being sent or received by its user.
