Is this vulnerability remotely exploitable?

Yes. If an attacker can obtain credentials or a role that allows editing module titles, or if such functionality is exposed to less-trusted users, they can craft a payload that will execute in the browser of any user who visits affected pages.

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

Typically the attacker needs at least the ability to create or edit modules or their titles, which is often an authenticated content-editor or similar role. In some deployments, misconfigured permissions could expand this capability to more users than intended.

What is the safest general fix pattern?

Treat titles and similar metadata as plain text by default, ensure all outputs are contextually encoded, and if richtext is required, pass it through a strict sanitizer that removes scripts, event handlers, and dangerous attributes before storage or rendering.
