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:** 1.0.3 - **Selected version is latest:** Yes - **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 source sends undisclosed runtime usage and paywall telemetry to the vendor, which warrants a warning under the telemetry rules. The reviewed flows do not show credentials or project data being sent to an unrelated host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-01T17:37:05.456Z - **Finished:** 2026-11-01T17:37:41.135Z - **Download time:** 1272 ms - **Static scan time:** 76 ms - **AI review time:** 34331 ms - **Total time:** 35679 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 telemetry reports free CLI use and paywall events to the package vendor. - **Trigger:** A free CLI run in an interactive terminal, or a paid feature attempt without a valid key; telemetry is skipped under documented environment opt-outs. - **Impact:** The vendor can track package usage and failed licensing attempts; the inspected payload does not include credentials or scanned file contents. - **Evidence paths:** cli.js, license.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T17:37:41.135Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** POSTs an event with the tool slug, invocation source and event reason to getreadystack.com/api/ev. - **Rationale:** The source sends undisclosed runtime usage and paywall telemetry to the vendor, which warrants a warning under the telemetry rules. The reviewed flows do not show credentials or project data being sent to an unrelated host. - **Files touched:** ~/.config/readystack/eu-data-residency-lint.json - **Network endpoints:** getreadystack.com/api/ev, getreadystack.com/api/lic, getreadystack.com/api/rules/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** After a free CLI run, interactive terminal use sends a usage event containing the tool slug and source to getreadystack.com/api/ev., When a paid feature has no valid key, the CLI or MCP path can send a paywall event with the tool slug, source and reason to the same endpoint., The telemetry is gated by interactive use and has opt-out checks for DO\_NOT\_TRACK, READYSTACK\_NO\_TELEMETRY and CI. - **Evidence against:** The event payload contains package-use and paywall fields, not discovered credentials, file contents or project data., License validation sends the user-supplied READYSTACK license key to the vendor's own getreadystack.com licensing endpoint. ## Affected versions and remediation This report applies to @readystack/eu-data-residency-lint@1.0.3. - Review the evidence and your use of @readystack/eu-data-residency-lint@1.0.3 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.
