GHSA-H6W7-QMCM-Q6XR RabbitMQ Java client: plaintext broker credentials leaked in exception message from ConnectionFactoryConfigurator.load()

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...

LiquidJS: ownPropertyOnly bypass for inherited array indices in first/last/join/reverse/slice/compact, `.first`/`.last`, negative index, and for-loop iteration

Summary LiquidJS’s ownPropertyOnly option is intended to prevent templates from reading inherited or prototype properties from scope data. With ownPropertyOnly: true, direct access such as: liquid a0 correctly blocks an inherited array index. However, the same inherited value is still disclosed...
