      "value": "Apache Polaris did not consistently validate storage locations supplied during table and view registration.\n\nAn authenticated principal with permission to register a table or view could, depending on the affected release and registration path, cause Polaris to use the catalog's storage credentials to read a caller-selected Iceberg metadata file before verifying that the file was within the catalog's allowed storage locations.\n\nIf the catalog's underlying credentials could read an object outside that boundary, this could disclose limited information from the object.\n\n\nPolaris could also accept registration metadata located within an allowed location that contained references to storage locations outside the allowed boundary.\n\nThis second condition did not itself cause Polaris to read the referenced external locations during registration.\n\n\nThe demonstrated impact is limited to confidentiality.\n\nNo unauthorized data modification or availability impact has been demonstrated.\n\n\nThe server-side read requires a deployment using S3 credential vending and an object outside the allowed locations that the catalog's underlying storage credentials can read.\n\nExploitation requires an authenticated principal with table- or view-registration privileges."

      "value": "Apache Polaris no validaba consistentemente las ubicaciones de almacenamiento proporcionadas durante el registro de tablas y vistas.\n\nUn principal autenticado con permiso para registrar una tabla o vista podría, dependiendo de la versión afectada y la ruta de registro, hacer que Polaris usara las credenciales de almacenamiento del catálogo para leer un archivo de metadatos de Iceberg seleccionado por el llamador antes de verificar que el archivo estuviera dentro de las ubicaciones de almacenamiento permitidas del catálogo.\n\nSi las credenciales subyacentes del catálogo pudieran leer un objeto fuera de ese límite, esto podría divulgar información limitada del objeto.\n\nPolaris también podría aceptar metadatos de registro ubicados dentro de una ubicación permitida que contenían referencias a ubicaciones de almacenamiento fuera del límite permitido.\n\nEsta segunda condición no causó por sí misma que Polaris leyera las ubicaciones externas referenciadas durante el registro.\n\nEl impacto demostrado se limita a la confidencialidad.\n\nNo se ha demostrado ninguna modificación de datos no autorizada o impacto en la disponibilidad.\n\nLa lectura del lado del servidor requiere una implementación que utilice la dispensación de credenciales S3 y un objeto fuera de las ubicaciones permitidas que las credenciales de almacenamiento subyacentes del catálogo puedan leer.\n\nLa explotación requiere un principal autenticado con privilegios de registro de tablas o vistas."
