Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.3.60 - **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 package has a legitimate CLI and MCP purpose, and it discloses automatic tool-error reporting with an opt-out. However, its error reports also include recent tool inputs and outputs, a collection detail not disclosed in the README, so this is suspicious runtime telemetry rather than a confirmed malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-11-03T06:45:45.035Z - **Finished:** 2026-11-03T06:46:58.129Z - **Download time:** 520 ms - **Static scan time:** 2475 ms - **AI review time:** 70097 ms - **Total time:** 73094 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:** Automatic MCP error reporting includes recent tool inputs and outputs, creating a risk of sending more agent-session content than the documented error-reporting purpose suggests. - **Trigger:** An MCP tool call fails while the Grum server is running. - **Impact:** Recent agent tool content may be disclosed to the package's service without the user separately choosing to send that content. - **Evidence paths:** grum.mjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-03T06:46:58.129Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The wrapper keeps recent tool-call inputs and outputs, then attaches them to an automatic error report sent to Grum's feedback API. Some token-like strings and email addresses are redacted, but the content is not otherwise excluded. - **Rationale:** The package has a legitimate CLI and MCP purpose, and it discloses automatic tool-error reporting with an opt-out. However, its error reports also include recent tool inputs and outputs, a collection detail not disclosed in the README, so this is suspicious runtime telemetry rather than a confirmed malicious attack. - **Files touched:** grum.mjs, ~/.config/grum/feedback/ - **Network endpoints:** https://app.grum.so/api/cli/feedback, GRUM\_API\_ORIGIN/api/cli/feedback ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes a Grum CLI and has no install lifecycle script; its stated purpose is repository design checks and agent integration., The MCP wrapper records tool names, inputs, and outputs; inputs are truncated to 600 characters and outputs to 1,500., When an MCP tool fails, the error path automatically reports it with the recent tool-call records attached; reports are posted to Grum's feedback endpoint., The README mentions tool-error reports and documents a GRUM\_FEEDBACK=off opt-out, but does not describe including recent tool inputs and outputs in those reports. - **Evidence against:** The package's CLI, MCP server, and feedback feature align with its stated repository design-checking purpose., The feedback endpoint is the package's own Grum service, and users can disable feedback and tool-error reports., No install-time lifecycle hook or install-time network activity was identified. ## Affected versions and remediation This report applies to @grum-os/cli@0.3.60. - Review the evidence and your use of @grum-os/cli@0.3.60 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.
