Potential fix for code scanning alert no. 10: Log Injection

[manuelesimi]

Potential fix for https://github.com/eipm/DispatcherSuite/security/code-scanning/10

To fix the issue, the user-provided topic parameter should be sanitized before being logged. This can be achieved by removing or replacing potentially harmful characters, such as newline characters, or by validating the input against a strict pattern (e.g., alphanumeric characters only). The best approach is to sanitize the topic parameter in the Sender.send method, ensuring that all usages of the parameter within the method are safe.

Steps to implement the fix:

1. Add a sanitization step for the topic parameter in the Sender.send method.
2. Use String.replace to remove newline characters or validate the input using a regex pattern.
3. Ensure that the sanitized topic is used in all log messages within the method.
