hashes (using Eksblowfish).
If you use the [[plugins/passwordauth]] plugin, I recommend upgrading to
-ikiwiki 2.48, installing the [[Authen::Passphrase]] perl module, and running
+ikiwiki 2.48, installing the [[cpan Authen::Passphrase]] perl module, and running
`ikiwiki-transition hashpassword` to replace all existing cleartext passwords
with strong blowfish hashes.
You might also consider changing to [[plugins/openid]], which does not
require ikiwiki deal with passwords at all, and does not involve users sending
passwords in cleartext over the net to log in, either.

+## Empty password security hole
+
+This hole allowed ikiwiki to accept logins using empty passwords, to openid
+accounts that didn't use a password. It was introduced in version 1.34, and
+fixed in version 2.48. The [bug](http://bugs.debian.org/483770) was
+discovered on 30 May 2008 and fixed the same day.
+
+I recommend upgrading to 2.48 immediatly if your wiki allows both password
+and openid logins.
