How broadly exploitable is this vulnerability?

Exploitation typically requires an authenticated user who can submit or configure enrichment URLs. Once that condition is met, the attack surface includes any internal or metadata endpoints reachable from the OpenObserve environment.

Does an attacker need elevated privileges or just any account?

The attacker needs whatever level of access is sufficient to control enrichment URLs. In many setups, this may be available to non-admin users who can define or modify enrichment configurations.

What is the safest general fix pattern?

Adopt an allowlist-based approach for outbound enrichment destinations, normalize and resolve all hostnames/IPs before making requests, and reject any URL that resolves to private, loopback, link-local, or metadata address ranges. Combine this with network-layer egress controls to sensitive endpoints.
