# dnsmgr: restricted users can read domains outside their permissions

Link for people: https://infrastack.ai/live/CVE-2026-129468 (this .md is for agents)

Netcccyun dnsmgr 2.18 before 2.22 has a missing authorization check on the POST /cloudflare/get_domain_default_line endpoint. A restricted sub-user or single-domain login can iterate the domain_id parameter to read DNS line lists and default lines for domains they should not see.

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

## Fix

- Move to `2.22` or later (the sources state 2.22 is the first fixed version).

## From the sources

Netcccyun dnsmgr 2.18 before 2.22 contains a missing authorization vulnerability in POST /cloudflare/get_domain_default_line that allows restricted users to access domains outside their permissions. Restricted sub-users or single-domain logins can iterate the domain_id parameter to enumerate panel domain ids and read each domain's DNS line list and default line.
