## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 14 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Unknown
- **Selected version:** 4.0.18
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection confirms a bundled provider key and a user-callable feature that sends model properties to the configured DeepSeek service. This supports a warning about key exposure and data disclosure, but does not establish an attack or malicious intent.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** The bundle exposes a hard-coded DeepSeek API key. The one-click encoding feature sends selected BIM model properties to DeepSeek when its start method is called; the source does not establish that this is malicious behavior.

- **Trigger:** Engine initialization creates the encoding helper; calling its start method triggers the external request.

- **Impact:** The published key may be reused outside the SDK, and invoking the feature discloses selected model properties to DeepSeek.

- **Evidence paths:** dist/chunks/EngineKernel-BucDRg23.js, dist/index.d.ts, package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-10-25T22:20:33.360Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The helper gathers matching model component properties and posts them to the DeepSeek chat completion endpoint with the bundled key as a bearer credential.

- **Rationale:** Source inspection confirms a bundled provider key and a user-callable feature that sends model properties to the configured DeepSeek service. This supports a warning about key exposure and data disclosure, but does not establish an attack or malicious intent.

- **Files touched:** dist/chunks/EngineKernel-BucDRg23.js, dist/index.d.ts, package.json

- **Network endpoints:** https://api.deepseek.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 72.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The distributed engine bundle contains a hard-coded DeepSeek API key and logs its prefix when the encoding helper is constructed., Calling the encoding helper’s start method gathers model component properties and sends them in a request to api.deepseek.com using that key., The SDK constructs the encoding helper as part of engine initialization, while the network request occurs through its separately callable start method.

- **Evidence against:** The package manifest points to the inspected engine bundle and declares no lifecycle scripts., The source shows the upload occurs through the one-click encoding feature, not during package installation or helper construction.

## Affected versions and remediation

This report applies to iflow-engine-base@4.0.18.

- Review the evidence and your use of iflow-engine-base@4.0.18 before allowing it. Restrict the permissions described in this report.
