Mattermost fails to properly sanitize the user object when updating the username, resulting in the password hash being included in the response body.
Solution:
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that 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.
