Is Flash Player EmuFlash safe?

Medium risk

Flash Player EmuFlash lets sandboxed Flash content send arbitrary web requests through the extension.

When a page opens a Flash object in its player, the sandboxed Flash runtime forwards fetch and XMLHttpRequest calls to the parent extension page. The parent performs those requests with the extension's <all_urls> host access and returns the response to the Flash frame, without checking the message origin. A Flash file opened from any website can therefore use this bridge to request URLs the page itself could not normally read.
