How exploitable is this vulnerability in practice?

Exploitability is high in environments where non-admin users can reach the admin notification target endpoints. If such access is available, a non-admin user can typically modify shared notification targets with only their regular access key and session token.

Does an attacker need admin credentials to exploit this issue?

No. The issue arises specifically because admin-level authorization is missing. Any authenticated non-admin user who can send requests to the affected endpoints can attempt to overwrite or manipulate shared notification targets.

What is the safest general fix pattern for this problem?

The safest fix is to ensure all admin handlers—including notification-related ones—invoke a central authorization routine (such as `validate_admin_request`) with a defined action or role requirement. This should be enforced consistently and ideally via shared middleware or framework components rather than per-handler ad hoc checks.
