Is this vulnerability remotely exploitable?

Yes. As described, an attacker can exploit the issue remotely by sending crafted input to any API or user interface that triggers the `_route_using_overviews` function, assuming that their content is incorporated into the prompt construction.

What level of access does an attacker need?

The attacker typically only needs the ability to supply or influence the text that becomes part of the overviews or user query handled by the LLM Prompt Handler. No privileged access to the host or the underlying model is required if the application already exposes a network-accessible interface.

What is the safest general fix pattern?

The most robust fix is to redesign prompt construction so that system and routing instructions are completely separated from user inputs and overviews, using structured roles and explicit delimiting. Avoid interpolating raw user text directly into instruction fields; instead, treat it as data that the model should analyze within a constrained context.
