Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## 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:** 4.1.13 - **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. The package’s encoding feature sends selected BIM properties to an external AI service using a key embedded in the distributed bundle. Because the transfer is feature-related and requires an explicit method call, the evidence supports a warning about undisclosed external processing rather than a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-30T20:13:55.880Z - **Finished:** 2026-10-30T20:15:10.826Z - **Download time:** 1266 ms - **Static scan time:** 15360 ms - **AI review time:** 58320 ms - **Total time:** 74946 ms 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 BIM encoding feature sends selected model properties to DeepSeek using a hard-coded API key, creating an undisclosed external data-processing risk. - **Trigger:** An application calls the public OneClickEncoding.start() method. - **Impact:** Selected BIM model metadata leaves the application and is processed by api.deepseek.com; the embedded API key is also exposed in the published package. - **Evidence paths:** dist/chunks/EngineKernel-CbL7CIqJ.js, dist/index.d.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-30T20:15:10.826Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The encoder collects selected component IDs and properties, batches them into prompts, and sends POST requests with the embedded key as a Bearer token. - **Rationale:** The package’s encoding feature sends selected BIM properties to an external AI service using a key embedded in the distributed bundle. Because the transfer is feature-related and requires an explicit method call, the evidence supports a warning about undisclosed external processing rather than a malicious verdict. - **Network endpoints:** api.deepseek.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The encoder embeds a DeepSeek API key in the package and logs its first eight characters when constructed., The public start() method gathers BIM component properties for encoding; this path is triggered by an explicit method call., The encoder posts those properties to api.deepseek.com using the embedded key. - **Evidence against:** The remote request is part of the package’s BIM encoding feature and does not run merely on import., The reviewed flow sends selected component properties, rather than credentials belonging to the package user. ## Affected versions and remediation This report applies to iflow-engine-base@4.1.13. - Review the evidence and your use of iflow-engine-base@4.1.13 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
