org.apache.pulsar:pulsar-client-original is vulnerable to man-in-the-middle attacks. The vulnerability exists because the library does not verify peer TLS certificates, even when `tlsAllowInsecureConnection` is disabled via configuration, which allows a remote attacker to take control of a machine `between` the client and the server, leading to MitM attacks.
