Is this vulnerability remotely exploitable?

Yes. An attacker can exploit it remotely by sending a crafted login URL to a victim. No direct network access to the victim's environment is required beyond the ability to deliver the link over email, chat, or a web page.

Does an attacker need the victim to be authenticated first?

Not strictly. The attack can work against users who are already logged in, or against users who follow the malicious link, complete the login flow, and are then redirected within the same browser session. The key is that the victim's browser processes the untrusted `callbackUrl`.

What is the safest general fix pattern for this issue?

The most robust pattern is to restrict post-login redirects to a predefined allowlist of trusted destinations, validate any `callbackUrl` against that list on the server or in a dedicated validation layer, and avoid passing raw query parameters directly into routing APIs.
