# NocoDB: empty admin password lets a stranger sign up as super admin

Link for people: https://infrastack.ai/live/CVE-2026-126273 (this .md is for agents)

NocoDB skips creating its super-admin account when the admin password environment variable is empty. On a fresh instance, an unauthenticated attacker can call the public signup endpoint first and receive Creator and Super Admin roles, which gives full administrative control.

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

## Affected

- vendor:nocodb affected range not listed fixed no fixed version listed
- npm:nocodb affected range not listed fixed no fixed version listed

## How to check

- Check the NocoDB version with the running image or package; affected versions are those before `2026.09.0`.
- Look for the admin password environment variable in your deployment config; if it is empty or unset on a fresh install, the instance is at risk.
- Check whether a super-admin account exists that you did not create.

## Fix

- NocoDB versions before `2026.09.0`: move to `2026.09.0` or later.

## Documents

- [advisory] Vendor advisory: github.com https://github.com/nocodb/nocodb/security/advisories/GHSA-mjxv-r6j7-m8gv
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/nocodb-before-2026.09.0-privilege-escalation-via-incomplete-admin-bootstrap

## From the sources

NocoDB before 2026.09.0 contains a privilege escalation vulnerability in initAdminFromEnv.ts that silently skips super-admin bootstrap when the admin password environment variable is empty. Unauthenticated attackers can call the public signup endpoint first on a fresh instance to receive Creator and Super Admin roles, gaining full administrative control.
