Following a successful connection handshake, the `Connection.Config.SASL` field stores the `Authentication` implementation state used to establish the session. \n\nFor standard `PLAIN` authentication, this state utilizes the `PlainAuth` struct, which defines both `Username` and `Password` as publicly exported, plaintext string fields. Because this sensitive data is retained permanently in-memory within an exported field structure, any peripheral code, internal package, reflective logger, dependency, or automated debugging utility with access to the core `*Connection` object can read and expose the raw credentials.\n\n---\n\n## Vulnerability Details\n\n### Mechanism\nThe vulnerability stems from the structural design of the configuration storage used during and after the AMQP handshake:\n\n```go\n// auth.go:21-23\ntype PlainAuth struct {\n    Username string\n    Password string  // exported plaintext\n}\n```\n\nWhen an application initializes a connection, the `PlainAuth` object is deeply nested inside the configuration structure (`Connection.Config`).
