Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged process and network behavior supports Grum's repository review features. Its background feedback reporting is disclosed, limited to Grum-related summaries and tool reports, and has a documented opt-out. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-02T15:05:37.950Z - **Finished:** 2026-11-02T15:06:48.512Z - **Download time:** 510 ms - **Static scan time:** 2546 ms - **AI review time:** 67504 ms - **Total time:** 70562 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:** No attack identified. The CLI uses Grum's service for its repository review features and disclosed feedback reporting. - **Trigger:** User-run CLI or MCP operations; feedback reports may queue after Grum tool failures. - **Impact:** No malicious impact identified; the observed network and file activity supports the package's stated features. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T15:06:48.512Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package sends review data and feedback to Grum's API. Feedback is documented and can be disabled with GRUM\_FEEDBACK=off. - **Rationale:** The flagged process and network behavior supports Grum's repository review features. Its background feedback reporting is disclosed, limited to Grum-related summaries and tool reports, and has a documented opt-out. - **Files touched:** ~/.config/grum/feedback/ - **Network endpoints:** app.grum.so ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The README describes Grum as checking repository design tokens and UI designs against a team-reviewed contract., The README discloses background feedback summaries and failed-tool reports, describes the data included and its sanitization, and documents GRUM\_FEEDBACK=off., The source sends feedback to Grum's /api/cli/feedback endpoint and supports disabling it through GRUM\_FEEDBACK or DO\_NOT\_TRACK., The README says checks can be posted to Grum, and documents when CI and report flags do so. - **Evidence against:** MCP tool failures can automatically queue reports containing recent Grum tool calls; this is disclosed in the README and can be disabled. ## Affected versions and remediation This report applies to @grum-os/cli@0.3.59. - Review the evidence and your use of @grum-os/cli@0.3.59 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.
