CVE-2026-67221: RabbitMQ AMQP 1.0 shovel password exposure in status API

CVE-2026-67221 · Severity: info · Published 2026-09-23

RabbitMQ is a message broker that routes data between applications. The Shovel plugin, which can forward messages between brokers using AMQP 1.0 connections, stores connection credentials (including passwords) in plaintext and exposes them through management APIs and command-line tools. A user with monitoring permissions can retrieve these passwords, compromising authentication to upstream or downstream message systems.

Technical details

The AMQP 1.0 shovel plugin stores raw connection URIs containing embedded credentials without sanitization, while the AMQP 0-9-1 shovel correctly strips credentials before storage. The exposed URIs are accessible via GET /api/shovels and rabbitmqctl shovel_status commands to users with the monitoring tag. This is a cleartext credential storage vulnerability (CWE-312) affecting Shovel configurations that use URI-embedded credentials.
