How easy is this vulnerability to exploit?

Exploitation is straightforward for anyone with a valid account. An attacker can intercept or craft API requests and change the `{familyId}` (and optionally `{status}`) in the URL to operate on other families' records without needing advanced skills.

Does an attacker need administrative access to exploit this issue?

No. Any authenticated API user can potentially exploit the vulnerability. The weakness lies in the absence of object-level authorization checks on the affected endpoints, not in misconfigured admin permissions.

What is the safest general fix pattern for this vulnerability class?

Implement consistent, centralized authorization checks for every resource-specific operation. Each API endpoint that accepts an ID should verify that the caller has explicit permission to act on that specific resource, using a shared policy or authorization layer rather than endpoint-specific ad hoc logic.
