    name: 'Content Audit <= 1.9.1 CSRF Stored XSS Shell Upload',
    desc: %(
      Versions up to and including 1.9.1 of the Content Audit plugin suffer
      from a CSRF and encoding issue, allowing for a JavaScript payload to
      be stored in the notes against a page.

      This module will create a link, which when clicked by an admin, will
      store the payload against all auditable items with an ID in the specified
      range. By default, Content Audit ships with only pages audited, but posts
      can also be audited. The payload will be executed the next time an admin
      views the page / post management area, with one of the infected items
      visible in the list.

      Note: If a specified post ID has not been yet assigned a post / page, the
      payload will be stored and executed when the ID is eventually assigned to
      a new post / page.
