registration.\n\n\nThe demonstrated impact is limited to confidentiality.\n\nNo unauthorized data\u00a0modification 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
