What is CVE-2026-77407?

The RabbitMQ amqp091-go client, prior to version 1.13.0, contains a vulnerability where passwords used during PlainAuth are retained as plaintext in the connection configuration after authentication. This occurs because the Connection.openComplete method fails to erase sensitive data, leading to potential exposure of credentials through various logging and monitoring tools. As a result, any application or utility with access to the Connection object can inadvertently log or capture these credentials, posing a security risk. The issue has been addressed in version 1.13.0.

Affected Version(s)

amqp091-go < 1.13.0
