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 14 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:** 2.14.3 - **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 package’s runtime analytics sends visitor/session activity with the embedding page’s hostname and referrer to its own service. The README discloses this behavior and provides opt-outs, so this warrants a telemetry warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-02T17:48:00.192Z - **Finished:** 2026-11-02T17:49:14.998Z - **Download time:** 2313 ms - **Static scan time:** 10406 ms - **AI review time:** 62083 ms - **Total time:** 74806 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:** Runtime analytics sends identifying embedding-page details to the package’s service. - **Trigger:** Viewer analytics runs during viewer use when analytics context is supplied; \`createViewerFromSceneId\` supplies that context. - **Impact:** The service can associate visitor/session activity with the embedding page’s hostname and referrer. - **Evidence paths:** dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-02T17:49:14.998Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Analytics requests include the embedding hostname and referrer with visitor/session identifiers and are posted to the service tracking endpoint. The README documents the behavior and opt-outs. - **Rationale:** The package’s runtime analytics sends visitor/session activity with the embedding page’s hostname and referrer to its own service. The README discloses this behavior and provides opt-outs, so this warrants a telemetry warning rather than a publish block. - **Files touched:** dist/index.js, README.md, package.json - **Network endpoints:** https://discover.storysplat.com/api/track-embed ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** Analytics payloads include the embedding page’s hostname and referrer, along with visitor and session identifiers., Runtime analytics is sent by POST to \`/api/track-embed\`., The README documents viewer analytics and identifies DNT, Global Privacy Control, query-string, and storage opt-outs., The analytics API defaults to \`https://discover.storysplat.com\`; the API URL can be configured through \`STORYSPLAT\_API\_URL\` or a window setting., The flagged \`atob\` helper decodes data into a browser Blob URL., The manifest has no install hook; \`prepublishOnly\` runs the build. - **Evidence against:** The package is described as a 3D scene viewer, and its network use includes fetching scenes and viewer assets., The README discloses the runtime tracking and provides opt-out controls., The base64 decoding helper is used to create Blob URLs, not to decode and execute code. ## Affected versions and remediation This report applies to storysplat-viewer@2.14.3. - Review the evidence and your use of storysplat-viewer@2.14.3 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.
