Short explanation
PowerDNS-Admin versions 0 < 2026.11.0 contain a missing authorization flaw in the apply_records handler of the /admin/template/<template>/apply endpoint. An authenticated User‑role account can modify shared zone templates and inject attacker‑chosen NS, MX, A or CNAME records into zones later created from them. A patch is available; upgrade to 2026.11.0 or later. CVSS scores differ between cvelist (5.3) and NVD (4.3).
Unauthorized modification of DNS templates can lead to malicious DNS records, traffic hijacking, and service disruption.
What should be done?
- Upgrade PowerDNS-Admin to version 2026.11.0 or newer
- Apply vendor‑provided patches
- Audit and revert unauthorized template modifications
- Restrict template modification to privileged administrators
