Technical details
The vulnerability exists in the Shovel worker component which logs the entire shovel state map without redacting decrypted credentials. The affected code path is triggered when an autodelete shovel (src-delete-after configured) completes shutdown. The rabbit_shovel_worker lacks a format_status callback to redact sensitive fields before logging at DEBUG level. Attack requires DEBUG logging enabled (non-default), Shovel plugin enabled, URI-embedded credentials, and read access to broker logs.
