|Security Alert - Please reset your npm registry account
|The security of the npm registry has just been upgraded. This corrects a known
|flaw which led to the leakage of the password_sha and salt fields. The good
|news is that the leak is plugged. The bad news is that it existed for quite a
|* Your password wasn't leaked, but the hash was. Still not great.
|* It's fixed now.
|* Reset your npm account at http://admin.npmjs.org/reset
|* I'm very sorry.
|* Email me at email@example.com if you have questions or would like to chew me out.
|You have every right to be upset.
|To do login, npm uses the /_users database in couchdb. By default, CouchDB
|prior to version 1.2.0 makes this database world-readable.
|Your password wasn't leaked. However, the password_sha hash and the salt was.
|This means that someone with lots of CPU power at their disposal could
|eventually crack it. If your password is relatively short, then less CPU power
|would be needed. If your password is a single dictionary word, then even less.
|What We Did About It
|The npm registry has been upgraded to Couchdb 1.2.
|In order to facilitate the use cases where npm needs to read a user's public
|info, the non-sensitive pieces of the user record are being copied to a
|/public_users database, and the rewrites have been changed to point to the
|This means that the npm client continues to work without changes, and that
|the problem is fixed at the source, rather than relying on adding additional
|layers. Any downstream replicants of the registry will continue to work with
|their (exposed) _users databases without any changes.
|Why Wasn't This Disclosed Sooner
|It seemed wise to fix the exposure before telling a few thousand people about
|it. Jason Smith and I deployed the fixes on Monday 2012-03-05. We waited a
|few days to make sure that it didn't cause any additional problems, and to test
|things out. So far, it looks solid.
|I'm very thankful to the handful of people who reported this to me discretely
|rather than create more drama than necessary.
|What You Should Do
|Here are the options:
|Do nothing. Least secure, most convenient. Probably not enough.
|If you used a very strong password (eg, some string at least 20 characters or
|so) for your npm account, then this might be ok. If it was something short,
|or something you use in multiple places, then please read on.
|Reset your npm password at http://admin.npmjs.org/reset
|It's a 3-step process. The thing emails you a link. You click the link. Then
|you remove the `_auth` line from your ~/.npmrc file, and run `npm adduser`
|to re-create your account. If you only used the password for npm, and not for
|anything else, then you're done.
|If you have an old account containing capital letters or spaces in the
|username, then you'll need to create a lowercase url-safe version and add it
|to your packages. Ping me on IRC and I'll help out. (There are only a few of
|Reset/change the password of any service that has the same password.
|Because your username and email address are part of the public npm registry
|data, someone could take the exposed password and try it on facebook, twitter,
|foursquare, HSBC, Bank of America, and so on. This would not be good.
|Once again, I'm very sorry about the exposure, and the inconvenience it causes
|for you. You have a right to be upset. Feel free to email me with your gripes
|and complaints, as well as any additional questions you might have, or if you
|have any problems resetting your password.
