  "details" : [ "A flaw was found in Apache Thrift. This vulnerability involves improper validation of server certificates, where the hostname presented in the certificate does not match the expected hostname. A remote attacker could exploit this to impersonate a legitimate server, potentially intercepting or altering sensitive communications and leading to unauthorized access or information disclosure." ],
