Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 1.64.0 - **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 install hook performs a guarded repair of an existing Codex wrapper, a concrete agent integration lifecycle risk. The metadata gate indicates prior opt-in, so the evidence supports a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-07T20:27:25.933Z - **Finished:** 2026-10-07T20:27:59.942Z - **Download time:** 1538 ms - **Static scan time:** 3456 ms - **AI review time:** 29012 ms - **Total time:** 34009 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 npm postinstall can repair a previously opted-in Codex launcher wrapper. The wrapper install path may move the real Codex executable and write a launcher wrapper. - **Trigger:** Installing the package with its postinstall active, when Codex wrapper metadata already exists and the package is installed under node\_modules. - **Impact:** A user's Codex launcher may be changed during package installation after a prior wrapper opt-in. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T20:27:59.942Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall calls a repair routine that checks wrapper metadata and may run the wrapper installer; the installer backs up the real Codex executable and writes the wrapper. - **Rationale:** The install hook performs a guarded repair of an existing Codex wrapper, a concrete agent integration lifecycle risk. The metadata gate indicates prior opt-in, so the evidence supports a warning rather than a block. - **Files touched:** dist/postinstall.js, dist/hooks/codex-wrapper.js, package.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs scripts/postinstall.cjs during installation., The postinstall path invokes a Codex wrapper repair unless skipped., Repair requires existing wrapper metadata, then can re-run wrapper installation for a package in node\_modules., Wrapper installation can move the Codex executable to a backup path., The init agent configuration changes are tied to explicit initialization behavior. - **Evidence against:** The wrapper repair is gated by metadata indicating a prior opt-in; first-time installation is directed to an explicit CLI command., The Claude and Codex postinstall messages are read-only nudges, and the init flow supports skipping automatic integrations. ## Affected versions and remediation This report applies to hippo-memory@1.64.0. - Review the evidence and your use of hippo-memory@1.64.0 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.
