CVE-2025-5961
The Migration, Backup, Staging – WPvivid Backup & Migration plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'wpvivid_upload_import_files' function in all versions up to, and including, 0.9.116. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. NOTE: Uploaded files are only accessible on WordPress instances running on the NGINX web server as the existing .htaccess within the target file upload folder prevents access on Apache servers.

Esto permite que atacantes autenticados, con acceso de administrador o superior, carguen archivos arbitrarios en el servidor del sitio afectado, lo que podría posibilitar la ejecución remota de código. NOTA: Los archivos subidos solo son accesibles en instancias de WordPress que se ejecutan en el servidor web NGINX, ya que el archivo .htaccess existente en la carpeta de carga del archivo de destino impide el acceso en servidores Apache."
