Doc Text:
A flaw was found in Apache Thrift. This vulnerability involves improper validation of a certificate with a host mismatch, which could allow a remote attacker to bypass security checks. By presenting a specially crafted certificate, an attacker may impersonate a legitimate server or client. This could lead to a security bypass, potentially enabling unauthorized access or information disclosure.
