Online petitions service Change.org has a website bug that's disclosing as many as 40,000 e-mail addresses that presumably belong to current or former subscribers.
 
The disclosure bug was active at the time this post was being prepared and is exploitable using the search box provided on the site or via Google or Bing.

this is totally wrong. There were much more than 100 email addresses from their own search engine on their website (not on another website) exposed.
