Is this vulnerability remotely exploitable?

Yes. If an attacker can induce a victim to use a session ID that the attacker controls or knows (for example, via pre-set cookies or crafted links), the attacker can later use that same ID to access the victim's authenticated session remotely.

What level of access does an attacker need to exploit this?

The attacker needs the ability to influence or predict the victim's session identifier before the victim logs in, or to operate in a context where they can share or control the browser environment (such as on a shared or compromised device).

What is the safest general fix pattern for this issue?

The most robust pattern is to regenerate the session ID immediately after successful authentication (and on any privilege elevation), invalidating the old identifier so that pre-login sessions cannot be reused in an authenticated state.
