Sprint planning, we spot a risk for one of the stories: An old client wants a new feature that relies on a third-party component that has not been included in our integration tests for the last 2 years.

The risk: It's probably not compatible with the new version of our system, if that's true, we'll need to make changes to our system before starting to work on the new feature, and setup integration testing.

Management: - Are you sure it's not compatible anymore?
Me: - No, we would need to bring both systems up and test if they work, there's no automation for that right now.
Mangement: - If you have not checked it's not a risk.
Me: (o_O) ? Whatever, I've warned you.

2 Days later: Our system does not work with this third-party system anymore, we can't finish the feature this sprint.
