GHSA-644f-hrff-mf96: Duplicate Advisory: Authentication Bypass via Default JWT Secret in NocoBase docker-compose Deployments

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-mv7p-34fv-4874. This link is maintained to preserve external references.

Original Description

A vulnerability was detected in nocobase up to 1.9.4/2.0.0-alpha.37. The affected element is an unknown function of the file nocobase\packages\core\auth\src\base\jwt-service.ts of the component JWT Service. The manipulation of the argument API_KEY results in use of hard-coded cryptographic key . The attack can be launched remotely. A high complexity level is associated with this attack. The exploitability is described as difficult. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Root Cause Analysis

The vulnerability lies in the use of a default, hardcoded JWT secret in NocoBase docker-compose deployments. The application's JwtService constructor would fall back to using the APP_KEY environment variable if no specific secret was provided. The default docker-compose.yml files provided by NocoBase used a weak, publicly known value for APP_KEY ('your-secret-key').

An attacker could leverage this knowledge to sign their own JWT tokens with the default secret, effectively bypassing authentication and gaining unauthorized access to the application. The patch addresses this by modifying the AuthManager to generate a strong, random, and persistent secret if one is not explicitly configured. This ensures that each installation uses a unique secret, preventing attackers from forging tokens.
