      "value": "The RESTful Content Syndication plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the ingest_image() function in versions 1.1.0 to 1.5.0. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. This requires the attacker have access to a defined third-party server as specified in the settings, so it is unlikely that this will be exploitable by contributor-level users, and more likely to be exploited by administrators who also have access to the plugin's settings."

      "value": "El plugin RESTful Content Syndication para WordPress es vulnerable a cargas de archivos arbitrarias debido a la falta de validación del tipo de archivo en la función ingest_image() en las versiones 1.1.0 a 1.5.0. Esto hace posible que atacantes autenticados, con acceso de nivel de Autor y superior, carguen archivos arbitrarios en el servidor del sitio afectado, lo que puede hacer posible la ejecución remota de código. Esto requiere que el atacante tenga acceso a un servidor de terceros definido, como se especifica en la configuración, por lo que es poco probable que esto sea explotable por usuarios de nivel de colaborador, y más probable que sea explotado por administradores que también tienen acceso a la configuración del plugin."
