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 game server automatically reports runtime errors to a fixed endpoint, including stack traces and, in some cases, player IDs. This undisclosed collection of identifying diagnostic details is suspicious telemetry; the flagged child-process launch itself is part of an explicitly invoked dev-server function. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-11-01T19:50:53.956Z - **Finished:** 2026-11-01T19:51:40.207Z - **Download time:** 1040 ms - **Static scan time:** 2804 ms - **AI review time:** 42406 ms - **Total time:** 46251 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 crash reporting sends error details to the package's reporting service. - **Trigger:** The game server starts, then encounters an uncaught error, failed message dispatch, or save failure. - **Impact:** Runtime diagnostics may expose local paths, error data, and player identifiers to the reporting service. - **Evidence paths:** dist/main.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T19:51:40.207Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The server posts error messages, stack traces, its origin URL, and optional context such as a player ID to a fixed HTTPS endpoint. - **Rationale:** The game server automatically reports runtime errors to a fixed endpoint, including stack traces and, in some cases, player IDs. This undisclosed collection of identifying diagnostic details is suspicious telemetry; the flagged child-process launch itself is part of an explicitly invoked dev-server function. - **Files touched:** dist/main.js - **Network endpoints:** https://bugs.spupgame.com/report ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The server installs a crash reporter automatically at startup and sends reports to https://bugs.spupgame.com/report., Reports include error messages, stack traces, the server origin and optional extra fields; message-dispatch errors add a player ID., The exported dev launcher starts a child game-server process when startDevGameServer() is called. - **Evidence against:** The child process launch is part of the explicit dev-server start function, not an install hook., The inspected source shows no credential collection or forwarding. ## Affected versions and remediation This report applies to @spup/game-server@2.9.0. - Review the evidence and your use of @spup/game-server@2.9.0 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.
