CVE-2026-3409: RCE — Patch Guide

Overview

A high-severity remote code execution vulnerability has been identified in the eosphoros-ai db-gpt software, version 0.7.5. This flaw allows an unauthenticated, remote attacker to inject and execute arbitrary code on affected systems by exploiting a weakness in the flow import functionality.

Vulnerability Details

The vulnerability exists within the /api/v1/serve/awel/flow/import endpoint. This component is responsible for importing workflow definitions. Due to improper handling of user-supplied files, an attacker can craft a malicious file that, when processed, exploits the importlib.machinery.SourceFileLoader.exec_module function. This bypasses security controls and allows the attacker’s code to run with the same privileges as the db-gpt application.

In simple terms, an attacker can send a specially crafted file to a specific URL on your server, and the application will mistakenly execute harmful commands contained within that file.

Impact

The impact of this vulnerability is severe. Successful exploitation can lead to:

• Full System Compromise: An attacker can execute any command, potentially gaining complete control over the server hosting db-gpt.
• Data Breach: Sensitive data processed or stored by the db-gpt application (like database credentials or query results) can be stolen.
• Service Disruption: Attackers could disrupt operations by deleting files or stopping services.
• Launchpad for Further Attacks: The compromised server could be used to attack other internal systems on your network.

The exploit for this vulnerability is publicly available, increasing the likelihood of widespread attack attempts.

Remediation and Mitigation

The vendor has not yet released an official patch. Due to the active exploitation and high severity, immediate action is required.

Primary Action: Update Immediately

• Upgrade: As soon as the vendor releases a patched version (later than 0.7.5), upgrade your installation immediately. Monitor the official eosphoros-ai db-gpt repository for security announcements.

Immediate Mitigations:

1. Restrict Network Access: If possible, restrict network access to the db-gpt application’s management API (port 5000 by default) so it is not reachable from the public internet. Use firewall rules or network security groups to allow access only from trusted, necessary IP ranges.
2. Disable or Protect the Endpoint: If the flow import feature is not essential for your operation, consider disabling the /api/v1/serve/awel/flow/import endpoint via application configuration or a reverse proxy (like Nginx) that blocks requests to this path.
3. Apply Principle of Least Privilege: Ensure the operating system user account running the db-gpt service has the minimum permissions required, limiting the potential damage from successful code execution.

General Recommendation: Until a patch is applied, consider the affected version (0.7.5) unsuitable for use in internet-facing or production environments. Continue to monitor the project’s official channels for a security fix.
