While being logged into Gmail with the brower interface, IF one opens
another tab/browser window and stumbles across an 'evil' site, the
'evil' site can inject a filter into the Filter List. The attacker can
then forward emails wherever they want via the filter.
The above site contains graphics that show how this is accomplished.

> fixed by Google.
