Password-exposing bug purged from LastPass extensions

'Developers of the LastPass password manager have patched a vulnerability that made it possible for websites to steal credentials for the last account the user logged into using the Chrome or Opera extension. The vulnerability was discovered late last month by Google Project Zero researcher Tavis Ormandy, who privately reported it to LastPass. In a write-up that became public on Sunday, Ormandy said the flaw stemmed from the way the extension generated popup windows. In certain situations, websites could produce a popup by creating an HTML iframe that linked to the Lastpass popupfilltab.html window rather than through the expected procedure of calling a function called do_popupregister(). In some cases, this unexpected method caused the popups to open with a password of the most recently visited site.' -- source: https://arstechnica.com/information-technology/2019/09/lastpass-fixes-bug-th...
