Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Destructive Action - **Selected version:** 4.5.4 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package has no install hook, and the risky operations are reachable through its explicit setup command. Automatic deletion of a matching database volume without a separate volume-specific confirmation remains a significant destructive risk, so warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-21T04:04:19.934Z - **Finished:** 2026-10-21T04:05:13.915Z - **Download time:** 771 ms - **Static scan time:** 848 ms - **AI review time:** 52360 ms - **Total time:** 53981 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 setup command can delete an existing Docker database volume with a predictable name during initialization. This is a consequential data-loss risk, though the inspected source does not establish a hidden or remote attack. - **Trigger:** A user runs \`kempo init\` and the CLI selects new-container mode. - **Impact:** Database contents in a matching existing volume can be permanently lost. - **Evidence paths:** bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T04:05:13.915Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI stops and removes the named container, removes the \`${dbName}\_postgres\_data\` volume, then starts Docker Compose. - **Rationale:** The package has no install hook, and the risky operations are reachable through its explicit setup command. Automatic deletion of a matching database volume without a separate volume-specific confirmation remains a significant destructive risk, so warn rather than block. - **Files touched:** bin/cli.js, project Docker volume \`${dbName}\_postgres\_data\`, project server/db/migrations ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes \`bin/cli.js\` as its \`kempo\` command, which accepts the explicit \`init\` action., When initializing a new container, the CLI stops and removes the named Docker container and deletes the corresponding named volume before recreating it; existing database data can be lost., The CLI also removes the project’s migration directory before running a forced schema push. - **Evidence against:** The manifest declares no install lifecycle hook; the destructive behavior is in the explicitly invoked setup command., The CLI asks before deleting listed project files when reinitializing an existing project, but that confirmation does not cover the Docker volume deletion. ## Affected versions and remediation This report applies to kempo@4.5.4. - Review the evidence and your use of kempo@4.5.4 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.
