@Iron-56 Can you please provide a scenario or instance where this global handler is required or an example of a sensitive information leak that currently occurs without this middleware.

I'm afraid I can’t share reproduction steps or concrete exploit scenarios publicly, since they would expose sensitive information.
I’m happy to provide full details privately to the maintainers when they are available.
