How widely exploitable is this vulnerability in practice?

Exploitability depends on how easily an attacker can obtain or predict valid session identifiers. In environments where session IDs might be exposed (e.g., weak randomness, logging, interception over unencrypted channels, or shared environments), the risk is significant because a single compromised token can grant agent-level access.

Does an attacker need authenticated access to exploit this issue?

Not necessarily. If session identifiers can be guessed or intercepted without prior authentication, an unauthenticated attacker might exploit the vulnerability. In other setups, an attacker may first need some level of access to capture or infer another agent's session ID.

What is the safest general fix pattern?

The most robust pattern is to enforce strong, cryptographic authentication of agents and bind each session to an authenticated identity, with authorization checks on every request. The server should never treat a session ID alone as proof of identity; instead, it should confirm that the caller is the rightful owner of the session and authorized for the requested operation.
