      Horde Cross Site Scripting Holes
    ------------------------------------------------------------------------

    SUMMARY

    The <http://www.horde.org> Horde Application Framework is "a
    general-purpose web application framework in PHP, providing classes for
    dealing with preferences, compression, browser detection, connection
    tracking, MIME handling, and more".

    Horde contains two XSS attacks that can be exploited through GET requests.
    Once exploited, these requests could be used to execute any JavaScript
    commands in the context of that user, potentially including but not
    limited to reading and deleting email, and stealing authentication tokens.
