CVE-2026-66068Hinoki check available

Credential disclosure via full Shovel state logging

Published Sep 23, 2026 · Updated Sep 23, 2026

Information disclosure in RabbitMQ Server allows local users with broker-log access to read Shovel URI credentials after autodeletion. When an autodelete Shovel completes, rabbit_shovel_behaviour logs the entire state map at DEBUG level after deobfuscated_uris places plaintext URIs in its uris field. Exposure requires the Shovel plugin, URI-embedded credentials, non-default DEBUG logging, an autodelete Shovel, and access to broker logs.
