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 reviewed helper uses a bundled credential for a user-invoked encoding feature and sends model data to its configured service. The exposed credential is a concrete security risk, but the inspected source does not support a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-25T22:15:07.630Z - **Finished:** 2026-10-25T22:17:48.508Z - **Download time:** 1281 ms - **Static scan time:** 26923 ms - **AI review time:** 132671 ms - **Total time:** 160878 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 distributed SDK embeds a fixed credential for its DeepSeek encoding helper. Its start method sends model property batches to that service using the credential, creating a risk that consumers can extract and reuse it. - **Trigger:** A caller invokes the exposed one-click encoding start method. - **Impact:** If the credential is active, package consumers may reuse it and consume the associated account quota. The reviewed behavior does not establish theft of consumer credentials or malicious intent. - **Evidence paths:** dist/bim-engine-sdk.umd.js, dist/chunks/engine-3d-B\_ZxiLB1.js, dist/index.d.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-25T22:17:48.508Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper posts model property data to the DeepSeek chat endpoint and includes the embedded credential as a bearer token. - **Rationale:** The reviewed helper uses a bundled credential for a user-invoked encoding feature and sends model data to its configured service. The exposed credential is a concrete security risk, but the inspected source does not support a malicious verdict. - **Files touched:** dist/bim-engine-sdk.umd.js, dist/chunks/engine-3d-B\_ZxiLB1.js, dist/index.d.ts - **Network endpoints:** https://api.deepseek.com/v1/chat/completions ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The distributed SDK embeds a fixed credential for its DeepSeek encoding helper., The helper sends model data to DeepSeek using that credential as a bearer token., Calling the exposed start method gathers model properties and passes them to the helper; this is a user-invoked feature., The package declares a browser SDK entrypoint, and its public types expose the encoding helper and start method. - **Evidence against:** The reviewed helper sends its request to the DeepSeek endpoint associated with the encoding feature; no consumer credential harvesting or unrelated recipient was established., The source reviewed does not establish malicious intent or an attack on consumer accounts. ## Affected versions and remediation This report applies to iflow-engine-base@3.12.9. - Review the evidence and your use of iflow-engine-base@3.12.9 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.
