Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 14 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 4.1.1 - **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. Inspected source shows an optional model encoding flow and no concrete malicious behavior. Clean certification is unavailable because the required 371 distinct citations exceed the 256 citation limit, so this remains manual review rather than a warning or block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-25T22:19:11.350Z - **Finished:** 2026-10-25T22:21:49.119Z - **Download time:** 4624 ms - **Static scan time:** 14504 ms - **AI review time:** 138639 ms - **Total time:** 157769 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:** No concrete malicious attack surface was established in the inspected code. The optional encoding feature sends selected model properties to its configured AI service when started. - **Trigger:** A caller invokes the model encoding start method. - **Impact:** Selected model data is transmitted to the AI service; the inspected path does not establish unrelated collection or malicious use. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T22:21:49.119Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The feature gathers model properties and submits them to the fixed DeepSeek chat endpoint with a configured or bundled API key. - **Rationale:** Inspected source shows an optional model encoding flow and no concrete malicious behavior. Clean certification is unavailable because the required 371 distinct citations exceed the 256 citation limit, so this remains manual review rather than a warning or block. - **Network endpoints:** https://api.deepseek.com/v1/chat/completions ### Review decision - **Verdict:** Manual Review - **Confidence:** 78.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Low - **AI review observations:** package.json points to the inspected runtime entrypoints and lists development, build, and test scripts., The encoding feature is exposed as an optional API with a constructor that accepts an API key., Calling start() gathers selected model component properties and passes them to the encoding request., The request sends the supplied content to the fixed DeepSeek chat endpoint using the configured or bundled key. - **Evidence against:** The inspected manifest contains no install lifecycle hook., The inspected request belongs to the explicit model encoding API; no unrelated credential collection or automatic install-time behavior was established. ## Affected versions and remediation This report applies to iflow-engine-base@4.1.1. - Review the evidence and your use of iflow-engine-base@4.1.1 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.
