Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SA-11 Developer Testing and Evaluation

addresses: CWE-74

Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.

SC-34 Non-modifiable Executable Programs

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

SC-44 Detonation Chambers

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

SI-10 Information Input Validation

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

SI-16 Memory Protection

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.

SI-4 System Monitoring

addresses: CWE-74

Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.

Why these techniques?

Remote code injection in public web endpoint (/api/v1/serve/awel/flow/import) using Python's SourceFileLoader.exec_module enables unauthenticated RCE, directly mapping to T1190 (Exploit Public-Facing Application) for initial access and T1059.006 (Python) for arbitrary code execution.

NVD Description

A security flaw has been discovered in eosphoros-ai db-gpt 0.7.5. Affected is the function importlib.machinery.SourceFileLoader.exec_module of the file /api/v1/serve/awel/flow/import of the component Flow Import Endpoint. Performing a manipulation as part of File results in code injection. The attack may be…

initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Deeper analysisAI

CVE-2026-3409 is a code injection vulnerability in eosphoros-ai db-gpt version 0.7.5. The issue resides in the Flow Import Endpoint at /api/v1/serve/awel/flow/import, specifically within the importlib.machinery.SourceFileLoader.exec_module function. Attackers can trigger the flaw by manipulating a File input, leading to arbitrary code execution.

The vulnerability carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), making it remotely exploitable over the network by unauthenticated attackers with low attack complexity and no user interaction required. Successful exploitation enables limited impacts on confidentiality, integrity, and availability, associated with CWE-74 (Improper Neutralization of Special Elements) and CWE-94 (Improper Control of Generation of Code).

VulDB advisories detail the issue and note that an exploit has been publicly released via a GitHub Gist. The vendor was contacted early for disclosure but provided no response, and no patches or official mitigations are available. Security practitioners should restrict access to the affected endpoint and monitor for anomalous file imports.

An exploit PoC is available publicly, increasing the risk of real-world attacks against exposed db-gpt instances. As part of eosphoros-ai's db-gpt, the flaw may impact AI-driven database tools.
