Google personal suggest bug exposed user web history

Google has restored its "personalized" search suggestions after purging the tool of a critical vulnerability that allowed attackers to steal a user's web history.

Personalized search suggestions were disabled on March 1, and they didn't return until April 20. Ordinarily, Google adds these personalized keyword suggestions to its generic suggestion list if you've turned on Google Web History, a service that stores your searches and page visits. The personalized suggestions are based on data from Web History.
