RabbitMQ Java client: plaintext broker credentials leaked in exception message from ConnectionFactoryConfigurator.load()
GitHub lists this reviewed advisory for com.rabbitmq:amqp-client. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

source listed<= 5.34.0
### Summary When property-file/Map-based `ConnectionFactory` setup fails while parsing the `uri` key, the library wraps the underlying exception with the raw connection string — including the plaintext username and password — baked verbatim into the new exception's message. ### Details `ConnectionFactoryConfigurator.load(ConnectionFactory, Map, String)` (`src/main/java/com/rabbitmq/client/ConnectionFactoryConfigurator.java`, lines 142-155): String uri = properties.get(prefix + "uri"); if (uri != null) { try { cf.setUri(uri); } catch (URISyntaxException e) { throw new IllegalArgumentException("Error while setting AMQP URI: " + uri, e); } catch (NoSuchAlgorithmException e) { throw new IllegalArgumentException("Error while setting AMQP URI: " + uri, e); } catch (KeyManagementException e) { throw new IllegalArgumentException("Error while setting AMQP URI: " + uri, e); } } `uri` is the full AMQP URI — `amqp(s)://username:password@host:port/vhost` — concatenated verbatim into the exception message on any of the three catch branches. No masking/redaction exists anywhere in
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
