      "value": "The PhastPress plugin for WordPress is vulnerable to Unauthenticated Arbitrary File Read via null byte injection in all versions up to, and including, 3.7. This is due to a discrepancy between the extension validation in `getExtensionForURL()` which operates on URL-decoded paths, and `appendNormalized()` which strips everything after a null byte before constructing the filesystem path. This makes it possible for unauthenticated attackers to read arbitrary files from the webroot, including wp-config.php, by appending a double URL-encoded null byte (%2500) followed by an allowed extension (.txt) to the file path."

      "value": "El plugin PhastPress para WordPress es vulnerable a Lectura arbitraria de archivos sin autenticación mediante inyección de byte nulo en todas las versiones hasta la versión 3.7 incluida. Esto se debe a una discrepancia entre la validación de la extensión en getExtensionForURL() que opera sobre rutas decodificadas de URL, y appendNormalized() que elimina todo lo que sigue a un byte nulo antes de construir la ruta del sistema de archivos. Esto permite a atacantes no autenticados leer archivos arbitrarios desde la raíz web, incluido wp-config.PHP, añadiendo un byte nulo doblemente codificado en URL (%2500) seguido de una extensión permitida (.txt) a la ruta del archivo."
