Descriptions

The Image Optimizer, Resizer and CDN – Sirv plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the sirv_upload_file_by_chanks AJAX action in all versions up to, and including, 7.2.6. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

El complemento Image Optimizer, Resizer y CDN – Sirv para WordPress es vulnerable a cargas de archivos arbitrarias debido a la falta de validación del tipo de archivo en la acción AJAX sirv_upload_file_by_chanks en todas las versiones hasta la 7.2.6 incluida. Esto hace posible que atacantes autenticados, con acceso de nivel de colaborador y superior, carguen archivos arbitrarios en el servidor del sitio afectado, lo que puede hacer posible la ejecución remota de código.
