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:** 0.2.13 - **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. Inspected source shows user-invoked agent configuration mutation, which warrants a warning under the supplied policy. Network and command execution support Grum design checks, and no concrete malicious chain was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-03T22:22:14.140Z - **Finished:** 2026-10-03T22:23:46.034Z - **Download time:** 1029 ms - **Static scan time:** 717 ms - **AI review time:** 90147 ms - **Total time:** 91894 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:** Explicit Cursor setup installs agent hooks, an MCP command, and persistent design guidance. This is a concrete agent configuration capability, but no confirmed malicious attack was established. - **Trigger:** The user runs grum init cursor; Cursor subsequently activates configured hooks or the MCP server. - **Impact:** Grum can influence agent workflows and execute as an agent tool after setup; later retrieval is not pinned to this reviewed version. - **Evidence paths:** grum.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-03T22:23:46.034Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI writes repository-local configuration and an always-applied rule. The default MCP command uses npx --yes, permitting later package retrieval without a separate installation prompt. - **Rationale:** Inspected source shows user-invoked agent configuration mutation, which warrants a warning under the supplied policy. Network and command execution support Grum design checks, and no concrete malicious chain was identified. - **Files touched:** .cursor/hooks.json, .cursor/mcp.json, .cursor/rules/grum-buttons.mdc, .gitignore - **Network endpoints:** https://app.grum.so ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json exposes the CLI without lifecycle scripts or runtime self-dependencies., The explicit grum init cursor command activates agent configuration setup., Setup writes repository-local Cursor hooks and MCP configuration., Configured hooks run Grum; the default MCP command can fetch Grum through npx --yes., Setup generates an always-applied Cursor design rule., Stored authentication tokens are checked against the selected service origin. - **Evidence against:** No concrete malicious execution or covert credential export was identified., Configuration setup is user-invoked and preserves unrelated hook entries. ## Affected versions and remediation This report applies to @grum-os/cli@0.2.13. - Review the evidence and your use of @grum-os/cli@0.2.13 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.
