Description
In the
craft\web\Requestclass the$ipHeadersproperty overwrites the default values set in the\yii\web\Requestclass. However the$secureHeadersproperty is not updated accordingly with the same headers.This oversight allows users to spoof their IP addresses. For instance, if someone sets a spoofed
Forwarded-Forheader to a random IP address, the methodCraft::$app->getRequest()->getUserIP()will return this spoofed IP address instead of the user's real IP. This happens because theForwarded-Forheader is not in the$secureHeadersproperty, making it vulnerable to manipulation.Tested with Craft version 4.8.7
