Description

RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, ?LOG_DEBUG("shutting down Shovel '~ts', ... Shovel state: ~tp", [Name, State]) formats the entire state map. The 'uris' field holds plaintext URIs after credentials_obfuscation:decrypt (called in rabbit_shovel_util:deobfuscated_uris/2). No format_status/1,2 callback exists in rabbit_shovel_worker to redact it. Triggered when an autodelete shovel (src-delete-after = N) completes. With DEBUG logging enabled, autodelete-shovel completion writes the full shovel state map , including decrypted amqp://user:password@host/ URIs , to the broker log file. Preconditions include Shovel plugin enabled with URI-embedded credentials DEBUG log level (non-default) Autodelete shovel configuration Attacker has log read access. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0.
