A request target starting with an at-sign ('@') changes the base to a RFC 3986 userinfo component.\n\nFor example, a rewrite base of \"https://example.com\" with the submitted request \"GET @192.168.1.2/\" will send a request to \"https://example.com@192.168.1.2/\", with the rendered content returned to the attacker.\n\nThis allows an attacker to access internal or restricted hosts that only the webserver has access to."
