> Not sure it's bug, but security breach. With expression language i can view
> content of sensitive parameter from parameter context. For example:
> # Create parameter context with sensitive parameter
> !image-2022-10-20-00-06-19-498.png!
> # Create variable with name of this sensitive parameter #\{sample}
> !image-2022-10-20-00-07-20-476.png!
> # Create simple flow with EL expression: ${secret:evaluateELString()}
> !image-2022-10-20-00-08-52-510.png!
> # Content of this flowfile will contain sensitive value from parameter
> !image-2022-10-20-00-09-57-913.png!
> I suppose evaluateELString shouldn't access to sensitive parameters.
