When you have setup your Yii2 website i noticed when some one goes to: ‘REQUEST_URI’ => ‘/%0A’, an error is thrown; “yii\base\ErrorException: Header may not contain more than a single header, new line detected in /usr/local/php7vendor/yiisoft/yii2/web/Response.php:374” is this normal?

Can you show your UrlManager config?

    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
        'suffix' => '/',
        'normalizer' => [
            'class' => 'yii\web\UrlNormalizer',
            'action' => YII_DEBUG?\yii\web\UrlNormalizer::ACTION_REDIRECT_TEMPORARY:\yii\web\UrlNormalizer::ACTION_REDIRECT_PERMANENT,
        ],
        'rules' => [
                //some rules here..
        ],
    ],

I have the same problem. This problem is actual only if parameter enablePrettyUrl is enabled. My URL for testing:

http://mydomain.com/data:image/svg+xml,<svg%20xmlns%3d"http%3a%2f%2fwww.w3.org%2f2000%2fsvg"%20width%3d"24"%20height%3d"24">%0a%20%20<g%20fill%3d"none"%20fill-rule%3d"evenodd"%20transform%3d"translate(3%204

(I don’t know why someone tried to go to this address)
