Overview
Affected versions of this package are vulnerable to Insufficiently Protected Credentials via the SendPamAuthPacketFactory process. An attacker can obtain sensitive authentication credentials by intercepting network traffic or acting as a man-in-the-middle server during the authentication process. This is only exploitable if connections are made over plain TCP (sslMode=DISABLE) or a TLS mode that does not properly verify server identity, and the attacker can occupy an on-path position or control the server to present an Authentication Switch Request for the dialog plugin.
Workaround
This vulnerability can be mitigated by connecting over verified TLS (set sslMode=verify-full) or using a local Unix socket, or by restricting permitted authentication plugins via restrictedAuth so dialog cannot be negotiated over an insecure transport.
