Is there meachincs in Cesium to bypass CORS blocks?

Hello there,
I am working on an project that uses 3rd party imagery provider with cesium. The request is blocked because of CORS unmatched origins, so I cannot show the 3rd party data.
Then I find out that the common solutions are:

  1. use a Chrome plugin, it simply overwrite the “Access-Control-Allow-Origin” header in the response.
  2. build a proxy server and overwrite the “Access-Control-Allow-Origin” header in the response, by yourself.

So I was wondering if Cesium has already implemented something similar? (as CORS blocks is a common issue of web APIs)
Or do I have to build my own proxy server and load the layers via proxy?
Thank you

TerriaJS has a proxy server GitHub - TerriaJS/terriajs-server: NodeJS server for TerriaJS, consisting of a CORS proxy, proj4 CRS lookup service, ogr2ogr conversion service, and express static server.
