# PowerDNS-Admin: any user can rewrite shared zone templates

Link for people: https://infrastack.ai/live/CVE-2026-125378 (this .md is for agents)

PowerDNS-Admin lets any authenticated User-role account replace the record set of a shared zone template through the apply_records handler. Records injected this way (NS, MX, A or CNAME) end up in every zone later created from that template.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed PowerDNS-Admin version; affected builds are those before `2026.11.0`
- Review who holds User-role accounts and whether zone templates are shared with them

## Fix

- PowerDNS-Admin: move to `2026.11.0` or later

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/powerdns-admin-before-2026.11.0-missing-authorization-via-template-apply-endpoint
- [fix] Patch: github.com https://github.com/PowerDNS-Admin/PowerDNS-Admin/commit/baa0a19730798dfac3dd6c2bdfad8616a80bc17a
- [fix] Release notes: github.com https://github.com/PowerDNS-Admin/PowerDNS-Admin/releases/tag/v2026.11.0

## From the sources

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.
