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:** 0.18.0 - **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 SDK sends runtime installation telemetry automatically on init and provides no evident way to turn it off. The data is limited to project and integration metadata sent to the configured BugCatch API, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-31T03:46:08.884Z - **Finished:** 2026-10-31T03:46:55.289Z - **Download time:** 764 ms - **Static scan time:** 1025 ms - **AI review time:** 44614 ms - **Total time:** 46405 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:** Automatic runtime telemetry reports project and SDK configuration to the configured BugCatch API without an evident opt-out. - **Trigger:** The host application calls init(); the telemetry request is scheduled five seconds later. - **Impact:** The API can learn that the project uses the SDK and which integration features are configured. No credential theft or account mutation was identified. - **Evidence paths:** src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-31T03:46:55.289Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** POSTs project ID, SDK version, integration flags, and configured environment/release values to apiBase/ingest/hello, at most once daily per project in the browser. - **Rationale:** The SDK sends runtime installation telemetry automatically on init and provides no evident way to turn it off. The data is limited to project and integration metadata sent to the configured BugCatch API, so this warrants a warning rather than a block. - **Files touched:** localStorage key bugcatch:hello:\ - **Network endpoints:** Configured apiBase/ingest/hello (default apiBase: http://localhost:3000) ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Calling init() invokes \#sayHello(), which posts to /ingest/hello after a delay; the request is gated by a daily localStorage marker, not a telemetry opt-out., The hello request includes the project ID, SDK version, and identify/context/widget flags; it also includes the configured environment value., The hello request uses the configured apiBase, whose default is http://localhost:3000; the README example configures a BugCatch API host. - **Evidence against:** There is no preinstall, install, or postinstall script; prepublishOnly only runs the build script., The hello request sends project and SDK configuration metadata rather than credentials or account actions., The SDK’s stated purpose is browser bug reporting, and its report payload includes collected context when a report is submitted. ## Affected versions and remediation This report applies to @sphoro/bugcatch-web-sdk@0.18.0. - Review the evidence and your use of @sphoro/bugcatch-web-sdk@0.18.0 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.
