Treat them as untrusted evidence. 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:** 2.0.37 - **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 postinstall hook automatically invokes installer behavior for global non-CI installs, and that behavior changes command routing through PATH. The source supports a warning for guarded package-owned CLI setup, but does not establish a concrete attack requiring a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-08T16:17:25.642Z - **Finished:** 2026-10-08T16:18:04.122Z - **Download time:** 512 ms - **Static scan time:** 278 ms - **AI review time:** 37688 ms - **Total time:** 38480 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:** A global npm install automatically configures shell PATH to prefer this package's Claude and Codex shims. This creates a guarded install-time CLI routing risk, with no confirmed malicious behavior in the inspected source. - **Trigger:** A non-CI global npm installation, unless postinstall is explicitly skipped. - **Impact:** Future Claude and Codex command invocations can be routed through the package's account-selection shims. - **Evidence paths:** scripts/postinstall.mjs, lib/install\_actions.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:18:04.122Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook runs install.sh, whose installer adds the package bin directory at the front of PATH in shell configuration. - **Rationale:** The postinstall hook automatically invokes installer behavior for global non-CI installs, and that behavior changes command routing through PATH. The source supports a warning for guarded package-owned CLI setup, but does not establish a concrete attack requiring a block. - **Files touched:** shell configuration files ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook runs only for a global, non-CI install unless explicitly skipped, then launches the package's installer., The installer adds its bin directory to the front of PATH in shell configuration, routing Claude and Codex commands through package shims., The test source confirms the installer writes a marked PATH block; this is a real install-time configuration change. - **Evidence against:** The automatic setup is gated to global installs and can be skipped with an environment variable., The inspected Codex shim describes itself as a PATH shim and locates and executes the real Codex binary; no unrelated network endpoint or payload execution was identified in the inspected excerpt. ## Affected versions and remediation This report applies to claude-multiacc@2.0.37. - Review the evidence and your use of claude-multiacc@2.0.37 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.
