Fix a dangling subdomain CNAME

dns-subdomain-takeover

A CNAME points at a service that no longer claims the name. Anyone can register it and serve their content from your subdomain. Remove it.

Why this matters

Your subdomain's CNAME points to a service that no longer exists. Anyone can register that service and serve content from your subdomain, including phishing pages or malware.
