Can another browser extension or password manager capture data from LastPass?
Unlike the default password manager that comes bundled with your browser, LastPass encrypts all saved password credentials. Further, it does not store the key to decrypt the credentials anywhere on your computer.
Only encrypted data is sent from your computer to LastPass, and the encrypted data itself is doubly encrypted using SSL.
However, once a password leaves LastPass (e.g. while autofilling on a webpage), it is no longer held within LastPass. At this point another password manager could capture the data.
