Exposing Swagger/OpenAPI documentation is primarily a risk if your API has underlying security flaws, as it gives attackers a precise roadmap to find them.
Those detail every endpoint, parameter, and data model, making it easier to discover and exploit vulnerabilities like broken access control or injection points.
While a perfectly secure API mitigates the danger, protecting your documentation is a critical layer of defense that forces attackers to work without a map.
