Description
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.

Executive Summary

This vulnerability is a privilege escalation flaw in NocoDB versions before 2026.09.0. When the admin password environment variable is empty, the system skips the super-admin bootstrap process. This allows unauthenticated attackers to exploit the public signup endpoint on a fresh instance, automatically receiving Creator and Super Admin roles, which grants full administrative control over the system.

Detection Guidance

Check NocoDB version with: docker inspect <container> | grep NOCODB_VERSION or npm list -g nocodb. If version is below 2026.09.0, the system is vulnerable. Monitor for unauthorized signup attempts or unexpected admin role assignments.

Impact Analysis

Unauthenticated attackers can gain full administrative access to your NocoDB instance during the initial setup phase. This means they can create, modify, or delete data, change configurations, and take complete control of the system without any authentication.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating compliance requirements for GDPR, HIPAA, and other regulations. It may result in data leaks, unauthorized modifications, and loss of control over sensitive information, potentially leading to legal and financial penalties.

Mitigation Strategies

Upgrade NocoDB to version 2026.09.0 or later immediately. Ensure admin password environment variable is set during deployment. Revoke any unauthorized admin roles created during the vulnerable period.
