## Ризик CSRF { #csrf-risk }

Ця поведінка за замовчуванням забезпечує захист від класу атак **Cross-Site Request Forgery (CSRF)** у дуже конкретному сценарії.

Ці атаки використовують той факт, що браузери дозволяють скриптам надсилати запити без виконання перевірки CORS preflight, коли вони:

	// Limits all body and header sizes to a maximum fixed limit
	setRequestLimitMiddleware,
	// Validate all the incoming requests.
	setRequestValidityMiddleware,
	// Add upload forwarding middleware for site replication
	setUploadForwardingMiddleware,
	// Add bucket forwarding middleware
	setBucketForwardingMiddleware,
	// Add new middlewares here.
}

// configureServer handler returns final handler for the http server.

            @Override
            public String getIndexFieldHost() {
                return "host";
            }

            @Override
            public String getIndexFieldSite() {
                return "site";
            }

            @Override
            public String getIndexFieldLastModified() {
                return "last_modified";
            }

            @Override

## CSRF-Risiko { #csrf-risk }

Dieses Standardverhalten schützt vor einer Klasse von **Cross-Site Request Forgery (CSRF)**-Angriffen in einem sehr spezifischen Szenario.

Diese Angriffe nutzen aus, dass Browser Skripte Requests senden lassen, ohne einen CORS-Preflight-Check durchzuführen, wenn sie:

        // mimetype
        defaultDataMap.put(fessConfig.getIndexFieldMimetype(), mimeType);
        // title
        // content
        // cache
        // digest
        // host
        // site
        // url
        // anchor
        // content_length
        // last_modified
        // id
        // virtual_host
        defaultDataMap.put(fessConfig.getIndexFieldVirtualHost(),

## CSRF Risk { #csrf-risk }

This default behavior provides protection against a class of **Cross-Site Request Forgery (CSRF)** attacks in a very specific scenario.

These attacks exploit the fact that browsers allow scripts to send requests without doing any CORS preflight check when they:

    .default(DEFAULT_TIMEOUT)
