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 CLI contains a real command-injection vulnerability when its project or database name contains shell syntax. Because it requires invoking setup with such a name and does not establish publisher-directed attack behavior, warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-21T04:03:38.712Z - **Finished:** 2026-10-21T04:04:33.625Z - **Download time:** 772 ms - **Static scan time:** 733 ms - **AI review time:** 53407 ms - **Total time:** 54913 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 init CLI passes a project name or entered database name into shell commands without escaping it. This creates a conditional local command-injection vulnerability; the source does not establish publisher-directed payload execution. - **Trigger:** A user invokes kempo init, setup creates a new container, and the project directory name or entered database name contains shell syntax. - **Impact:** A crafted name can cause additional local shell commands to run during setup. - **Evidence paths:** bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T04:04:33.625Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI interpolates the name into docker stop and docker rm commands executed through execSync. - **Rationale:** The CLI contains a real command-injection vulnerability when its project or database name contains shell syntax. Because it requires invoking setup with such a name and does not establish publisher-directed attack behavior, warn rather than block. - **Files touched:** bin/cli.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for warning:** The CLI accepts only the init command and sets defaults from a project name derived from the current directory., In interactive setup, the entered database name becomes the container name; with defaults, the project directory name is used., The new-container path interpolates that name into shell commands, creating a conditional command-injection vulnerability. - **Evidence against:** The risky commands are reached through the user-invoked init setup path and only when creating a new container. ## Affected versions and remediation This report applies to kempo@4.4.0. - Review the evidence and your use of kempo@4.4.0 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.
