Doc Text:
A flaw was found in Google Chrome. This cross-site request forgery (CSRF) vulnerability, which tricks a web browser into executing an unwanted action on a trusted site where the user is authenticated, specifically affects the DeviceBoundSessionCredentials feature. A remote attacker can exploit this by enticing a user to visit a specially crafted HTML page, leading to a bypass of the web origin policy. This bypass could allow unauthorized actions to be performed on behalf of the user.
