VULNERABILITY DETAILS
Normally we should type our computer's password to access the passwords saved by chrome.
However.it can be bypassed.
Follow the step:
1.chrome://settings/
2.click "Show advanced settings..." at the bottom of the screen.
3.click "Manage passwords" below the "Passwords and forms" item.
4.move mouse to any item of the hided password in the "Password" window.
5.click the cipher password and click "Show" button.
6.mac ox alert "Google Chrome is trying to show passwords.Type your password to allow this"

But if we open a webpage with saved password ,Chrome will autofill password.
then we use "Inspect elements" and focus on the password elements. change the attributes of the 'input' from "type=password" to "type=text". The saved password will show plaintext password.

so,we can easily and soundlessly access all of the current user's accounts password saved by Chrome  if we use this logic issue and urls in step3 as long as we have the change to access user's computer.
