    CVE-2020-1765
    
        An improper control of parameters allows the spoofing of the from

        AgentTicketForward, AgentTicketBounce.
    
    CVE-2020-1766
    
        Due to improper handling of uploaded images it is possible in very
        unlikely and rare conditions to force the agents browser to execute
        malicious javascript from a special crafted SVG file rendered as
        inline jpg file.
    
    CVE-2020-1767
    
        Unauthorized view of drafts, change the text completely and send it
        in the name of draft owner. For the customer it will not be visible

    We recommend that you upgrade your otrs2 packages.
