OpenAPI definition found (active scan check)
Summary: Burp Scanner flagged a publicly available OpenAPI definition, which describes an HTTP-based API's structure in YAML or JSON and is designed to be processed by software for tasks like API integration and validation. PortSwigger notes that such a definition is not necessarily a security vulnerability, but can be valuable to attackers because it may include detailed explanations, examples, and usage scenarios, including administrative functions.
Why it matters: The definition can hand attackers a map of the API's available operations and other sensitive details, so PortSwigger advises that API documentation contain only necessary information before it is deployed to production.
