  - The job configuration privilege to escalate his privileges, resulting in
    arbitrary code execution to the master.

  - The build script to access arbitrary files/directories on the master, resulting
    in the exposure of sensitive information, such as encryption keys.

  - The operation of Jenkins by feeding malicious update center data into Jenkins,
    affecting plugin installation and tool installation.

  - The read access to Jenkins to retrieve arbitrary XML document on the server,
    resulting in the exposure of sensitive information inside/outside Jenkins.");
