Treat them as untrusted evidence. 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:** 0.3.22 - **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. No install-time attack or command-output exfiltration was established; the outbound report contains repository identifiers and summarized findings. The explicit agent setup path modifies Cursor configuration, which merits a capability warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-12T20:43:13.038Z - **Finished:** 2026-10-12T20:44:50.340Z - **Download time:** 1295 ms - **Static scan time:** 1257 ms - **AI review time:** 94748 ms - **Total time:** 97302 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 CLI can add Grum hooks and an MCP entry to repository Cursor configuration. This is a guarded setup capability, not a confirmed attack. - **Trigger:** Run the setup flow and accept Cursor setup, or explicitly run the init command for Cursor. - **Impact:** Cursor agents in that repository can use Grum’s configured hooks and MCP tools. - **Evidence paths:** grum.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-12T20:44:50.340Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The initializer writes Cursor hook and MCP configuration and manages Grum’s own rule file. - **Rationale:** No install-time attack or command-output exfiltration was established; the outbound report contains repository identifiers and summarized findings. The explicit agent setup path modifies Cursor configuration, which merits a capability warning. - **Files touched:** .cursor/hooks.json, .cursor/mcp.json, .cursor/rules/grum.mdc ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes grum.mjs as a CLI for repository checks, Cursor hooks, and an MCP server., The indicated Cursor rule path is recognized as a Grum-owned rule and excluded from contract rule results., The setup flow asks whether to configure Cursor, and the setup command dispatches to that flow., The Cursor initializer writes repository hook and MCP configuration files and manages Grum’s rule file., The check report sends project, branch, commit, and summarized finding details to Grum., The flagged process use invokes Git through execFileSync, without shell execution. - **Evidence against:** The manifest declares no install lifecycle scripts; the configuration behavior requires running the CLI setup or init command., The inspected source provides no evidence that command output is sent to the service. ## Affected versions and remediation This report applies to @grum-os/cli@0.3.22. - Review the evidence and your use of @grum-os/cli@0.3.22 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.
