How exploitable is this vulnerability in practice?

It can be highly exploitable if an attacker can reliably induce victims to use attacker-controlled session IDs, for example via crafted links or shared systems. In such scenarios, it may lead directly to account takeover without knowing the victim's password.

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

The attacker needs network access to the web interface and the ability to establish a session and then get the victim to adopt that same session ID. They do not need valid credentials for the victim's account.

What is the safest general fix pattern for this issue?

The most robust fix is to regenerate a new, unpredictable session identifier on successful authentication and on any privilege elevation, invalidating the previous session to prevent reuse.
