Treat them as untrusted evidence. 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:** 1.0.1 - **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 sends undisclosed runtime usage telemetry to its own service during free CLI runs, so it is suspicious under the telemetry rule. The reported fields are limited and the request can be disabled, with no evidence of credential or file exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-31T14:06:30.934Z - **Finished:** 2026-10-31T14:07:08.564Z - **Download time:** 775 ms - **Static scan time:** 75 ms - **AI review time:** 36779 ms - **Total time:** 37630 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:** Undisclosed runtime usage telemetry is sent during free CLI use; no data exfiltration or other attack was identified. - **Trigger:** A free CLI run in a TTY or MCP session, unless telemetry is opted out or CI is detected. - **Impact:** The vendor learns that the tool was used in a free run; the event does not include file contents or credentials. - **Evidence paths:** cli.js, license.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-10-31T14:07:08.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Posts a minimal usage event to the package vendor’s endpoint. - **Rationale:** The package sends undisclosed runtime usage telemetry to its own service during free CLI runs, so it is suspicious under the telemetry rule. The reported fields are limited and the request can be disabled, with no evidence of credential or file exfiltration. - **Files touched:** ~/.config/readystack/dsfinv-k-export-lint.json (or READYSTACK\_HOME/dsfinv-k-export-lint.json) - **Network endpoints:** getreadystack.com/api/ev, api.polar.sh/v1/customer-portal/license-keys/validate, getreadystack.com/api/rules/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** A free CLI run automatically sends a \`use\` event to \`getreadystack.com/api/ev\`., That event contains only the package slug, CLI source, and a fixed \`free\` reason; no file contents or credentials are included., The event is suppressed by telemetry opt-out variables and in CI, and is sent only for a TTY or MCP session., The README describes the free CLI checks but does not disclose this usage reporting. - **Evidence against:** The manifest defines a CLI entry point and no lifecycle scripts., License validation sends the user-provided or stored Readystack license key to Polar’s license-validation endpoint, consistent with the paid feature., The rules feed uses the license key with Readystack’s own service; feed data is parsed as JSON rules., The usage event carries limited tool-use metadata rather than host, user, project, or file data. ## Affected versions and remediation This report applies to @readystack/dsfinv-k-export-lint@1.0.1. - Review the evidence and your use of @readystack/dsfinv-k-export-lint@1.0.1 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.
