[org.jvnet.hudson.plugins:jabber] Passwords stored in plain text by Jenkins Jabber (XMPP) notifier and control Plugin

Jabber (XMPP) notifier and control Plugin 1.41 and earlier stores passwords unencrypted in its global configuration file hudson.plugins.jabber.im.transport.JabberPublisher.xml on the Jenkins controller as part of its configuration.

These passwords can be viewed by users with access to the Jenkins controller file system.

Jabber (XMPP) notifier and control Plugin 1.42 stores passwords encrypted once its configuration is saved again.
