CVE-2026-77407— RabbitMQ amqp091-go: Plaintext Credential Exposure via Exported PLAIN Authentication Struct Fields
Quick assessment
Affected
rabbitmq amqp091-go
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
RabbitMQ 的 amqp091-go 是一个 Go 语言的 AMQP 0.9.1 客户端。在 1.13.0 版本之前， 中定义的 PlainAuth 值在 PLAIN 认证握手成功之后，会以导出的明文字段形式保留在 中。 中的 方法并未清除这些值。任何能够访问 对象的代码（包括反射式日志记录器、应用程序性能监控代理、调试工具和 panic 处理程序）都可以通过遍历配置项，将凭据暴露到日志或状态快照中。这些凭据在连接的生命周期内持续存在，而不是在认证完成后被清除。该问题已在 1.13.0 版本中修复。

Vulnerability Title
RabbitMQ amqp091-go: Plaintext Credential Exposure via Exported PLAIN Authentication Struct Fields
Source: CVE Program / CVE List V5
Vulnerability Description
RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, PlainAuth values defined in auth.go retain passwords as exported plaintext fields in Connection.Config.SASL after a successful PLAIN authentication handshake. The Connection.openComplete method in connection.go does not clear those values. Code with access to the Connection object, including reflective loggers, application performance monitoring agents, debugging utilities, and panic handlers, can traverse the configuration and expose the credentials to logs or state captures. The credential remains available for the lifetime of the connection instead of being cleared after authentication. This issue is fixed in version 1.13.0.
