Is Spotify Adblock safe?

Medium risk

Spotify Adblock lets cross-origin frames read the current page URL and inject elements into the page.

Spotify Adblock installs a content script on most websites and listens for window messages without checking the sender's origin. A cross-origin child frame can ask the extension to return the top page URL or append caller-chosen elements into the page. On open.spotify.com, it also rewrites the Content-Security-Policy response header to allow inline scripts and eval.
