Bloglines Can Reveal Feeds For Other GMail Users
I wanted to pass on this warning I read on Cybernet Technology News.
Full details are contained in the above link but to summarise, the problem concerns people who have burned their GMail feed using FeedBurner. If you don’t make the feed private then it means anyone could potentially have access to sensitive information in your email inbox such as a username and password to access a web site, etc.
Whilst you are not able to go straight from the feed to look at the complete email, once subscribed you can read the subject and the first line of any email sent to these addresses. That can often be enough to reveal sensitive information.
Here is a screenshot from Bloglines showing other people’s GMail feeds.
