How broadly exploitable is this SSRF bypass?

Exploitability depends on how Directus is configured and which features are exposed; it becomes meaningful when attackers can control or influence URLs used for server-initiated requests and when internal services are reachable from the Directus host.

Does an attacker need authenticated access to exploit this issue?

Not necessarily. Some deployments may expose functionality that triggers outbound requests without authentication, while others restrict such actions to authenticated users or specific roles. The key requirement is the ability to supply or modify the target URL.

What is the safest general fix pattern for this kind of vulnerability?

The most robust fix is to normalize all destination addresses, strictly block local and private networks (including IPv4-mapped IPv6 and other encodings), and, where possible, restrict outbound requests to a curated allow-list of domains or services.
