The eBay owned popular digital payment and money transfer service, PayPal has been found to be vulnerable to a critical web application vulnerability that could allow an attacker to take control over users' PayPal account with just a click, affecting more than 156 millions PayPal users.

 

An Egyptian security researcher, Yasser H. Ali has discovered three critical vulnerabilities in PayPal website including CSRF, Auth token bypass and Resetting the security question, which could be used by cybercriminals in the targeted attacks.
