Authentication bypass by spoofing vulnerability in Apache APISIX. When a Route's configured headers carry a caller identity and the OpenAPI document declares
the same header, a caller can act as another identity against the
upstream API. This issue affects Apache APISIX: from 3.19.0 before 3.20.0.
Users are recommended to upgrade to version 3.20.0, which fixes the issue.
