How broadly exploitable is this vulnerability?

It can be exploited by any unauthenticated party who has network access to the affected Weblate instance and can guess or enumerate screenshot filenames, potentially at internet scale if the instance is publicly exposed.

Does an attacker need an account or special permissions?

No explicit account is required; the weakness arises because screenshot resources can be retrieved directly by URL without verifying authentication or project membership.

What is the safest general fix pattern?

The most robust approach is to route all screenshot access through the application, enforce proper authentication and authorization checks, and avoid direct static serving of any screenshots that are not explicitly intended to be public.
