      "value": "The Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the 'validate' function and insufficient blocklisting on the 'wpcf7_antiscript_file_name' function in versions up to, and including, 5.8.3. This makes it possible for authenticated attackers with editor-level capabilities or above to upload arbitrary files on the affected site's server, but due to the htaccess configuration, remote code cannot be executed in most cases. By default, the file will be deleted from the server immediately. However, in some cases, other plugins may make it possible for the file to live on the server longer. This can make remote code execution possible when combined with another vulnerability, such as local file inclusion."

      "value": "El complemento Contact Form 7 para WordPress es vulnerable a cargas de archivos arbitrarias debido a una validaci\u00f3n insuficiente del tipo de archivo en la funci\u00f3n 'validar' y a una lista de bloqueo insuficiente en la funci\u00f3n 'wpcf7_antiscript_file_name' en versiones hasta la 5.8.3 incluida. Esto hace posible que atacantes autenticados con capacidades de nivel de editor o superior carguen archivos arbitrarios en el servidor del sitio afectado, pero debido a la configuraci\u00f3n de htaccess, el c\u00f3digo remoto no se puede ejecutar en la mayor\u00eda de los casos. De forma predeterminada, el archivo se eliminar\u00e1 del servidor inmediatamente. Sin embargo, en algunos casos, otros complementos pueden hacer posible que el archivo permanezca m\u00e1s tiempo en el servidor. Esto puede hacer posible la ejecuci\u00f3n remota de c\u00f3digo cuando se combina con otra vulnerabilidad, como la inclusi\u00f3n de archivos locales."
