  "details" : [ "In Tornado before 6.5.5, cookie attribute injection could occur because the domain, path, and samesite arguments to .RequestHandler.set_cookie were not checked for crafted characters.", "A flaw was found in Tornado. A remote attacker could exploit this vulnerability by injecting specially crafted characters into the `domain`, `path`, and `samesite` arguments when setting cookies. This could lead to cookie attribute injection, potentially allowing for information disclosure or manipulation of client-side data." ],
