Cross-Site Scripting (XSS) is a well-known vulnerability that has been around for a long time and can be used to steal sessions, create fake logins and carry out actions as someone else, etc. In addition, many users are unaware of the potential dangers associated with their browser’s credential autofill feature. This attack vector is not new, but it is unknown to many people and as we investigated further we found that the dangers were extensive.
