Description
PowerDNS-Admin before 2026.11.0 contains a missing authorization vulnerability in the apply_records handler for /admin/template/<template>/apply that lets any authenticated User-role account modify shared zone templates. Attackers can replace a template's record set by name, injecting attacker-chosen NS, MX, A or CNAME records into every zone later created from it.
