How broadly exploitable is this vulnerability?

The vulnerability is highly exploitable wherever the ChurchCRM setup wizard is exposed to untrusted networks. Any unauthenticated user who can reach the installation page during setup can potentially exploit it, which is why it is rated critical.

Does an attacker need authentication or an existing account to exploit this?

No. The issue is pre-authentication; exploitation occurs before any user accounts are created or login checks are enforced. Network reachability to the setup wizard is the primary requirement.

What is the safest general fix pattern for this type of issue?

The safest approach is to eliminate dynamic code generation from user-controlled input entirely. Treat installation parameters strictly as data, store them in non-executable configuration formats, and ensure any necessary interpolation applies rigorous escaping and validation without ever passing user values into constructs that PHP will execute as code.
