Is this vulnerability remotely exploitable?

Yes. Any user who can create or modify submission titles, display names, or user identifiers can inject malicious content. Exploitation occurs when an organiser, typically over the internet, uses the backend search interface and the crafted record appears in their results.

Does an attacker need organiser or admin access to exploit this?

No. The attacker only needs the ability to control one of the affected fields, which may be possible for ordinary registered users or speakers. The organiser/admin role is only required on the victim side, whose browser executes the injected script when using the search.

What is the safest general fix pattern for this type of issue?

The safest pattern is to treat all user-controlled data as untrusted and render it using APIs or templating mechanisms that escape content by default. Avoid `innerHTML` for such data, rely on `textContent` or equivalent text-only bindings, and use explicit, well-reviewed sanitization when raw HTML truly must be supported.
