Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The manifest has no install lifecycle hook, and the CLI’s process execution occurs during explicit project initialization. The flagged dynamic import serves request-selected route files, while inspected dependency install behavior is consistent with native addon setup. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-21T04:02:51.608Z - **Finished:** 2026-10-21T04:03:34.660Z - **Download time:** 761 ms - **Static scan time:** 832 ms - **AI review time:** 41458 ms - **Total time:** 43052 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 attack was identified in the inspected source. The flagged process execution is part of the explicit project initialization command. - **Trigger:** A user runs the \`kempo init\` command. - **Impact:** These inspected actions support project setup and request handling; no confirmed attack surface was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-21T04:03:34.660Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI scaffolds project files, installs Kempo, and configures the database; middleware imports a matching route file to handle a request. - **Rationale:** The manifest has no install lifecycle hook, and the CLI’s process execution occurs during explicit project initialization. The flagged dynamic import serves request-selected route files, while inspected dependency install behavior is consistent with native addon setup. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package manifest lists build, database, admin and test scripts; it has no install lifecycle hook., The CLI exits unless the caller explicitly runs the init command, and installs Kempo as a setup step., The flagged middleware import loads a route file to handle a request., The inspected bcrypt install script runs node-gyp-build; dotenv and drizzle-kit show no install script, and drizzle-kit’s inspected entrypoint only exports defineConfig. ## Affected versions and remediation This report applies to kempo@4.2.39. - Review the evidence and your use of kempo@4.2.39 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.
