An attacker that can intercept and modify traffic between the client and the server can impersonate the server by presenting a valid certificate for a different domain. \n\n\nPlease note the classic version of HttpClient is not affected by this vulnerability. \n\nAffected users are recommended to upgrade to at least version 5.6.4, which fixes the issue.",
