Workaround

Kylin reflects the `Origin` header and allow credentials to be sent cross-origin in the default configuration. The preflight OPTIONS request: ``` OPTIONS /kylin/api/projects HTTP/1.1 Host: localhost:7070 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:94.0) Gecko/20100101 Firefox/94.0 Accept: */* Accept-Language: en-US Accept-Encoding: gzip, deflate Access-Control-Request-Method: POST Access-Control-Request-Headers: content-type Referer: http://b49b-95-62-58-48.ngrok.io/ Origin: http://b49b-95-62-58-48.ngrok.io Connection: keep-alive Cache-Control: max-age=0 ``` Will be replied with: ``` HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Access-Control-Allow-Origin: http://b49b-95-62-58-48.ngrok.io Access-Control-Allow-Credentials: true Vary: Origin Access-Control-Allow-Methods: DELETE, POST, GET, OPTIONS, PUT Access-Control-Allow-Headers: Authorization, Origin, No-Cache, X-Requested-With, Cache-Control, Accept, X-E4m-With, If-Modified-Since, Pragma, Last-Modified, Expires, Content-Type Content-Length: 0 ``` Users of Kylin 2.x & Kylin 3.x should upgrade to 3.1.3 or apply patch https://github.com/apache/kylin/pull/1782.
