Imagine this scenario: You deprovision a web resource that was created for a product or promotion that no longer exists. You believe that you've removed all traces from public access . but have you?
The Domain Name System (DNS) record - the CNAME - may still be out there. If so, an attacker may find this 'dangling' CNAME in public DNS records and hijack the subdomain. Now they can create a well-laid trap for redirecting traffic to an impersonated site that they can use for phishing or other malicious schemes.
