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. A fixed-looking DeepSeek key is embedded in the client bundle and used for requests to DeepSeek, creating credential exposure and possible reuse risk. The transfer requires invoking the encoding API, so the source supports a warning but not a package block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-25T22:14:56.801Z - **Finished:** 2026-10-25T22:17:59.700Z - **Download time:** 1518 ms - **Static scan time:** 23620 ms - **AI review time:** 157760 ms - **Total time:** 182899 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 client bundle includes a fixed-looking provider key. When a consumer invokes the encoding feature, selected model properties are sent to DeepSeek. - **Trigger:** A consumer calls oneClickEncoding.start() after creating the engine. - **Impact:** Consumers can recover and potentially reuse the embedded key; model properties leave the application when encoding runs. The source does not establish that the key is valid or that the transfer is malicious. - **Evidence paths:** dist/chunks/engine-3d-COo\_NGsu.js, dist/index.d.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-25T22:17:59.700Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The feature gathers properties from selected model components and posts them to the DeepSeek chat endpoint using the embedded key as a bearer credential. - **Rationale:** A fixed-looking DeepSeek key is embedded in the client bundle and used for requests to DeepSeek, creating credential exposure and possible reuse risk. The transfer requires invoking the encoding API, so the source supports a warning but not a package block. - **Files touched:** dist/chunks/engine-3d-COo\_NGsu.js, dist/index.d.ts, package.json - **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 shipped engine bundle contains a fixed-looking DeepSeek API key and uses api.deepseek.com as its default endpoint., Calling the encoding feature collects model component properties and posts them with that key to DeepSeek., The package exposes the feature through the engine API and a callable start method, so the transfer is user-invoked rather than an install-time action., The package manifest lists development and build scripts, with no install lifecycle hook. - **Evidence against:** Source ties the external request to the encoding feature; inspected code does not send the key to an unrelated recipient., The manifest has no install lifecycle hook, and the SDK constructs the encoding helper without calling start. ## Affected versions and remediation This report applies to iflow-engine-base@3.12.19. - Review the evidence and your use of iflow-engine-base@3.12.19 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.
