Remote Code Execution in Budibase via Malicious Plugin

Publication date: 2026-08-28

Last updated on: 2026-08-28

Assigner: VulnCheck

Description
Budibase versions before 3.41.3 contain a remote code execution vulnerability in plugin handling that allows authenticated admin users to execute arbitrary code by uploading a malicious plugin tarball. The server calls eval() on plugin JavaScript files without sandboxing in the main Node.js process, enabling attackers to exfiltrate environment variables and credentials with root privileges in default deployments.

Executive Summary

Budibase versions before 3.41.3 have a remote code execution flaw in plugin handling. Authenticated admin users can upload a malicious plugin tarball to execute arbitrary code. The server uses eval() on plugin JavaScript files without sandboxing in the main Node.js process, allowing attackers to access sensitive data like environment variables and credentials with root privileges.

Detection Guidance

Check Budibase server logs for unusual plugin uploads or JavaScript file executions. Monitor for unexpected network connections or data exfiltration attempts from the Node.js process. Review admin user activity logs for suspicious plugin installations.

Impact Analysis

An attacker with admin access could execute malicious code on the server, leading to data breaches, unauthorized system access, or complete server compromise. This could result in stolen credentials, sensitive data exposure, or disruption of services.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or health data, violating GDPR and HIPAA requirements for data protection and confidentiality. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Upgrade Budibase to version 3.41.3 or later immediately. Restrict admin user access to only necessary personnel. Disable plugin upload functionality if not required. Implement network segmentation to limit potential damage from exploitation.
