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. Source confirms explicit-command agent configuration changes and an unpinned executable integration, warranting a capability warning. The absence of npm lifecycle hooks and the inspected consent and credential handling do not support blocking as malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-06T21:41:13.553Z - **Finished:** 2026-10-06T21:42:10.560Z - **Download time:** 1286 ms - **Static scan time:** 940 ms - **AI review time:** 54780 ms - **Total time:** 57007 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 CLI setup changes repository-local Cursor agent configuration. This is a concrete agent-control capability, but inspection did not establish a malicious attack. - **Trigger:** Running grum init cursor or accepting Cursor configuration during setup. - **Impact:** Changes agent instructions and tool execution, with later tool launches potentially resolving newer CLI code. - **Evidence paths:** grum.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-06T21:42:10.560Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Writes hooks, a Grum MCP server entry, and an always-applied rule; the MCP command invokes an unpinned npm package. - **Rationale:** Source confirms explicit-command agent configuration changes and an unpinned executable integration, warranting a capability warning. The absence of npm lifecycle hooks and the inspected consent and credential handling do not support blocking as malware. - **Files touched:** .cursor/hooks.json, .cursor/mcp.json, .cursor/rules/grum.mdc, .gitignore - **Network endpoints:** https://app.grum.so ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json exposes grum.mjs as the CLI and declares no lifecycle scripts or runtime dependencies., The explicit init cursor command writes repository-local Cursor hooks and MCP configuration., Interactive setup asks whether to configure Cursor agents before invoking configuration writes., Installed MCP and pre-commit commands use an unpinned npx invocation, allowing later executions to resolve a newer CLI release., The generated always-applied Cursor rule directs agents to call Grum contract and check tools., Saved Grum credentials are selected by API origin and checked against that origin. - **Evidence against:** No unconsented npm install-time agent configuration mutation was found., Inspected Git output and outbound requests support design checks and review reports; they do not establish covert exfiltration., Configuration helpers preserve unrelated hooks and MCP server entries. ## Affected versions and remediation This report applies to @grum-os/cli@0.3.10. - Review the evidence and your use of @grum-os/cli@0.3.10 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.
