DESCRIPTION:
A security issue has been reported in ikiwiki, which can be exploited
by malicious people to bypass certain security restrictions.

The security issue is caused due to an error in the "openid" and
"passwordauth" plugins when processing login requests with empty
passwords. This can be exploited to gain access to user accounts that
have an associated "openid" account without a configured password.

Successful exploitation requires that the "openid" and "passwordauth"
plugins are enabled.

The security issue is reported in versions 1.34 and later, prior to
2.48.

SOLUTION:
Update to version 2.48.
