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:** 2.35.2 - **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 package’s guest and host messaging behavior fits its stated purpose, and I found no install-time attack or credential theft. However, instance creation enables runtime diagnostics that include page identifiers and are sent to a remote endpoint without an apparent opt-in, so this warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-03T18:33:45.189Z - **Finished:** 2026-11-03T18:34:39.952Z - **Download time:** 763 ms - **Static scan time:** 229 ms - **AI review time:** 53770 ms - **Total time:** 54763 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 diagnostics telemetry is enabled when an SSFGuest instance is created. - **Trigger:** Application code constructs SSFGuest. - **Impact:** The service can receive page URLs, paths, titles, application identifiers, metrics, and error details without a separate telemetry opt-in. - **Evidence paths:** dist/cjs/guest.js, .lpm-dependency-evidence-3ef88294-906c-40ae-96a5-fa240146fa6f/0/npm-linux/dist/cjs/webvitals.js, .lpm-dependency-evidence-3ef88294-906c-40ae-96a5-fa240146fa6f/0/npm-linux/dist/cjs/diagnosticsEndpoint.js, .lpm-dependency-evidence-3ef88294-906c-40ae-96a5-fa240146fa6f/0/npm-linux/dist/cjs/transport/http.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T18:34:39.952Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The constructor registers web-vitals and error reporting and logs the page URL; the default HTTP transport posts logs to the ICE diagnostics service. - **Rationale:** The package’s guest and host messaging behavior fits its stated purpose, and I found no install-time attack or credential theft. However, instance creation enables runtime diagnostics that include page identifiers and are sent to a remote endpoint without an apparent opt-in, so this warrants a warning. - **Network endpoints:** https://api.mortgagetech.ice.com/diagnostics/v2/logging ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Constructing SSFGuest automatically registers web-vitals reporting and logs the current page URL., Web-vitals reports include product and app URLs, paths, page titles, and application IDs., The diagnostics logger sends log bodies by POST to the default ICE diagnostics endpoint. - **Evidence against:** The package is a browser guest library, and its host communication and session keep-alive behavior fit that purpose., No install lifecycle hook or automatic credential collection was identified. ## Affected versions and remediation This report applies to @elliemae/ssf-guest@2.35.2. - Review the evidence and your use of @elliemae/ssf-guest@2.35.2 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.
