Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 1.52.7 - **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. Classify as suspicious because the explicit \`hippo init\` command can modify agent configuration, and static analysis coverage is incomplete. The inspected npm postinstall behavior does not establish unconsented first-time agent setup or another concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-09T05:43:47.195Z - **Finished:** 2026-10-09T05:44:39.402Z - **Download time:** 513 ms - **Static scan time:** 3823 ms - **AI review time:** 47869 ms - **Total time:** 52207 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 source shows an agent configuration capability, not a confirmed attack. Running \`hippo init\` can add Hippo instructions to existing agent instruction files in the current project. - **Trigger:** A user runs \`hippo init\` without \`--no-hooks\`. - **Impact:** This changes project agent configuration; the inspected path is explicitly user-invoked and does not establish malicious behavior. - **Evidence paths:** dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T05:44:39.402Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI detects agent markers in the current project and patches existing instruction files with Hippo hook instructions. - **Rationale:** Classify as suspicious because the explicit \`hippo init\` command can modify agent configuration, and static analysis coverage is incomplete. The inspected npm postinstall behavior does not establish unconsented first-time agent setup or another concrete attack. - **Files touched:** dist/cli.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI’s \`init\` path invokes hook setup unless \`--no-hooks\` is set., Hook setup detects agent files in the current project and patches existing instruction files, adding Hippo hook instructions., The npm \`postinstall\` script loads the package postinstall module., The postinstall module repairs a previously installed Codex wrapper and prints setup guidance; it does not perform first-time wrapper installation., The package’s agent integration behavior is a user-invoked configuration capability, so the reviewed source does not establish an active attack. - **Evidence against:** The explicit \`hippo init\` command can modify existing agent instruction files in the current project, making this a real agent-configuration capability., Static analysis reported parse errors in several files, so a clean classification is not supported by complete analysis coverage. ## Affected versions and remediation This report applies to hippo-memory@1.52.7. - Review the evidence and your use of hippo-memory@1.52.7 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.
