  "details": "When curl retrieves and parses cookies from an HTTP(S) server, it accepts\ncookies using control codes (byte values below 32). When cookies that contain\nsuch control codes are later sent back to an HTTP(S) server, it might make the\nserver return a 400 response. Effectively allowing a \"sister site\" to deny\nservice to siblings."
