If a user is instructed to open an image in a new tab (right click -> open in new tab, or copy the URL and paste it in the URL bar), an the image payload is executed on the domain hosting the app (app.wire.com). In particular, if an image contains malicious code in addition to the actual picture, this code is executed on app.wire.com. This allows the attacker to fully control the user account.
