Summary
PowerDNS-Admin, before the fixed release, lets any authenticated User-role account modify shared zone templates through the template apply endpoint, which is missing an authorization check. An attacker can reach it remotely with a low-privilege login and no user action, then inject attacker-chosen NS, MX, A, or CNAME records into zones later created from the affected template.
