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 scanner’s runtime installation signal is part of the user-invoked project setup flow. However, that flow can remove a matching Docker volume without a specific confirmation, so the data-loss risk warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-21T04:04:46.805Z - **Finished:** 2026-10-21T04:05:46.994Z - **Download time:** 792 ms - **Static scan time:** 942 ms - **AI review time:** 58454 ms - **Total time:** 60189 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 CLI can remove an existing Docker database container and volume when initializing a new database. This creates a data-loss risk if the selected names match resources containing prior data. - **Trigger:** A user runs the init command with Docker available and setup proceeds in new-container mode. - **Impact:** Data in a matching Docker volume may be permanently deleted. Noninteractive mode skips the existing-container selection prompt. - **Evidence paths:** bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T04:05:46.994Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI stops and removes the selected container, then removes a volume named from the database name before starting Docker Compose. - **Rationale:** The scanner’s runtime installation signal is part of the user-invoked project setup flow. However, that flow can remove a matching Docker volume without a specific confirmation, so the data-loss risk warrants a warning. - **Files touched:** bin/cli.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI is activated by a user running its init command; it also installs Kempo into the selected project during setup., When setup creates a new database container, it stops and removes a container with the selected name and removes the correspondingly named Docker volume. The noninteractive mode skips the existing-container selection prompt, so prior database data could be removed without a specific warning., For an existing project with a public directory, noninteractive mode exits; interactive reinitialization asks for confirmation before deleting listed project files. - **Evidence against:** The destructive behavior is confined to the setup CLI and is not an install-time package lifecycle action., Interactive setup lets the user review existing containers and explicitly confirms reinitialization of an existing project. These safeguards do not specifically confirm removal of a matching Docker volume. ## Affected versions and remediation This report applies to kempo@4.6.0. - Review the evidence and your use of kempo@4.6.0 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.
