Is Dark Mode for Chrome safe?

Medium risk

Dark Mode for Chrome lets websites route page-supplied stylesheet URLs through the extension.

When native dark mode processes a page, the extension reads stylesheet links from the page and asks its background script to fetch cross-origin HTTP(S) URLs. It writes the returned stylesheet text back into the page DOM as a new style element, so a website can supply a URL and read the fetched content from the page.
