id: CVE-2024-6651

info:
  name: WordPress File Upload Plugin < 4.24.8 - Cross-Site Scripting
  author: ritikchaddha
  severity: high
  description: |
    The WordPress File Upload plugin before version 4.24.8 contains a reflected cross-site scripting vulnerability. The plugin does not properly sanitize and escape the 'dir' parameter in the file browser page before outputting it back, which could allow attackers to execute arbitrary JavaScript code in an administrator's browser context.
