Is this vulnerability remotely exploitable?

It can be, if remote users can influence configuration values that Dynaconf processes through the @Jinja resolver. For example, if user input is persisted into configuration-like storage or mapped into environment variables consumed by Dynaconf, an attacker may trigger SSTI remotely.

Does exploitation require authenticated access?

That depends on how configuration data is populated in your application. If only trusted operators can modify configuration sources, the risk is primarily insider or supply-chain driven. If external or unauthenticated inputs influence configuration, then unauthenticated exploitation may be possible.

What is the safest general fix pattern?

The safest approach is to avoid evaluating templates on configuration values altogether, or at least strictly disable template processing for any data that can originate from untrusted sources. Where evaluation is unavoidable, constrain the template environment, expose only minimal, non-dangerous functions, and treat templates as a privileged feature controlled solely by trusted administrators.
