    "summary": "RabbitMQ is a messaging and streaming broker. From 4.0.0 until 4.3.3, 4.2.9, 4.1.14, and 4.0.23, Shovel does not format state logged by the crash reporter and can leave unencrypted credentials in a crash dump file. the shovel worker genserver processes does not implement the formatstatus/2 callback. When these processes crash (e.g., due to network partitions, connection failures), the OTP SASL error handler writes the full process state , including plaintext AMQP passwords and URIs , to the error log. This is particularly severe for the shovel worker, which stores deobfuscated plaintext URIs (including amqp://user:password@host format) in its genserver state for the entire process Automatic Credential Exposure: Shovel worker crashes (common during network partitions) automatically write plaintext upstream/downstream passwords to error logs No Special Configuration Needed: Unlike DEBUG logging, SASL error reports are always active Broad. This issue is fixed in versions 4.3.3, 4.2.9, 4.1.14, and 4.0.23.",
