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. Static inspection found an embedded service credential in the distributed client, creating a risk of unauthorized reuse if it remains active. The model-data transfer is part of an explicit runtime feature, and the inspected source does not establish a separate attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 80.0% - **Started:** 2026-10-25T22:18:11.720Z - **Finished:** 2026-10-25T22:21:07.274Z - **Download time:** 1015 ms - **Static scan time:** 12474 ms - **AI review time:** 162064 ms - **Total time:** 175554 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 client contains a DeepSeek API credential that is exposed to package consumers. The encoding feature also sends selected model properties to DeepSeek when its start method is called; the source does not show that this transfer is a hidden attack. - **Trigger:** Creating the engine constructs the helper; calling its start method triggers model-property collection and network requests. - **Impact:** If the embedded key is active, package consumers could reuse it, potentially causing unauthorized service use; invoking the feature also shares selected model properties with DeepSeek. - **Evidence paths:** dist/chunks/engine-3d-DAEOqkkS.js - **Review source:** ai\_review - **Reviewed:** 2026-10-25T22:21:07.274Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper uses a built-in default key as a bearer credential for DeepSeek chat requests and logs part of the key during construction. - **Rationale:** Static inspection found an embedded service credential in the distributed client, creating a risk of unauthorized reuse if it remains active. The model-data transfer is part of an explicit runtime feature, and the inspected source does not establish a separate attack. - **Network endpoints:** https://api.deepseek.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 80.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The client code supplies a built-in API key to the encoding helper and logs part of it when the helper is constructed., Calling the helper's start method collects selected model properties and submits them in chat requests to DeepSeek using that key., The helper is attached to the engine during construction, while the network transfer occurs in its separate start method. - **Evidence against:** The inspected transfer is tied to an explicit runtime feature; it does not establish an install-time attack or theft of consumer credentials., The source does not establish whether the embedded service key is active or what access it permits. ## Affected versions and remediation This report applies to iflow-engine-base@4.0.15. - Review the evidence and your use of iflow-engine-base@4.0.15 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.
