Deferred Deferred - Pending Action

Command Injection in NocoBase AI-Powered Platform

Publication date: 2026-07-15

Last updated on: 2026-07-18

Assigner: GitHub, Inc.

Description

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to 2.1.19, NocoBase @nocobase/plugin-backups restored PostgreSQL backups by interpolating the database.schema value from _metadata.json into shell command strings executed with Node.js child_process.exec(), allowing a backup-management user restoring a crafted backup to execute commands as the NocoBase server process. This vulnerability is fixed in 2.1.19.

Attack-Flow Graph

Executive Summary

NocoBase versions before 2.1.19 have a vulnerability in the backup restoration process. When restoring PostgreSQL backups, the system interpolates the database.schema value from _metadata.json into shell command strings executed via Node.js child_process.exec(). This allows a user with backup management privileges to execute arbitrary commands as the NocoBase server process by crafting a malicious backup file.

Detection Guidance

Check NocoBase version with 'npm list @nocobase/plugin-backups' or inspect backup files for _metadata.json containing executable commands in database.schema. Review server logs for unexpected child_process.exec() calls during backup restoration.

Impact Analysis

This vulnerability allows an attacker with backup management access to execute arbitrary commands on the server running NocoBase. This could lead to full system compromise, data theft, or disruption of services. Users running affected versions should update immediately to mitigate risk.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR's integrity and confidentiality requirements or HIPAA's security rules. Organizations must ensure systems are patched to maintain compliance and protect sensitive data.

Mitigation Strategies

Upgrade NocoBase to version 2.1.19 or later immediately. Restrict backup management user permissions to prevent unauthorized backup restoration. Monitor for suspicious activity in server logs.
