The SVG WG decided that the SVG Integration spec will take care of it.

It depends who creates/references the resource. I'm not sure what you mean by the above, but, concretely, the SVGDocumentResource case in CachedResourceLoader::canRequest calls ContentSecurityPolicy::allowImageFromSource: https://chromium.googlesource.com/chromium/blink/+/master/Source/core/loader/cache/CachedResourceLoader.cpp That means SVGDocumentResource is controlled by img-src, at least in this implementation.
