RabbitMQ Java Client Credential Disclosure via URI Parsing Error

Publication date: 2026-10-06

Last updated on: 2026-10-06

Assigner: GitHub, Inc.

Description
The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.35.0, ConnectionFactoryConfigurator.load() includes the raw uri value in wrapped exceptions when AMQP URI parsing fails. Because the URI may contain a plaintext username and password, startup logs, application performance monitoring systems, CI logs, and copied stack traces can disclose broker credentials to users who should not have access to them. This issue is fixed in version 5.35.0.

Executive Summary

The RabbitMQ Java client library before version 5.35.0 has a flaw in ConnectionFactoryConfigurator.load(). When AMQP URI parsing fails, it includes the raw URI value in wrapped exceptions. Since URIs may contain plaintext usernames and passwords, this can expose sensitive credentials in logs or stack traces.

Detection Guidance

This vulnerability is related to credential exposure in RabbitMQ Java client logs. To detect it, inspect application startup logs, CI logs, or monitoring systems for RabbitMQ connection URIs containing plaintext credentials. Check if your RabbitMQ Java client version is below 5.35.0.

Impact Analysis

If you use RabbitMQ Java client versions before 5.35.0, attackers with access to logs, CI outputs, or stack traces could extract plaintext credentials. This may lead to unauthorized access to RabbitMQ brokers, data breaches, or further exploitation of connected systems.

Compliance Impact

This vulnerability can lead to unauthorized access or data exposure, violating GDPR (data protection) and HIPAA (health data privacy) requirements. Failure to protect credentials may result in regulatory fines, legal liabilities, and reputational damage due to non-compliance.

Mitigation Strategies

Upgrade the RabbitMQ Java client library to version 5.35.0 or later to fix the credential exposure issue. Review and rotate any exposed credentials if plaintext credentials were logged before the upgrade.
