In OpenStack Murano through 16.0.0, when YAQL before 3.0.0 is used, the Murano service's MuranoPL extension to the YAQL language fails to sanitize the supplied environment, leading to potential leakage of sensitive service account information.
The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.
