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 server automatically sends runtime error details, including stack traces and its configured URL, to a fixed vendor endpoint without visible disclosure or an opt-out. This is undisclosed runtime telemetry, so the package is suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 92.0% - **Started:** 2026-11-01T19:50:54.149Z - **Finished:** 2026-11-01T19:51:47.417Z - **Download time:** 1037 ms - **Static scan time:** 2620 ms - **AI review time:** 49610 ms - **Total time:** 53268 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 telemetry in the game server. - **Trigger:** Starting the server installs the reporter; uncaught exceptions, unhandled rejections, and other server errors trigger reports. - **Impact:** Error reports may disclose local paths or other details present in messages and stack traces; no credential collection or unrelated collector was identified. - **Evidence paths:** dist/main.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T19:51:47.417Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The server POSTs error messages, stack traces, build version, and its configured URL to https://bugs.spupgame.com/report. - **Rationale:** The server automatically sends runtime error details, including stack traces and its configured URL, to a fixed vendor endpoint without visible disclosure or an opt-out. This is undisclosed runtime telemetry, so the package is suspicious rather than malicious. - **Network endpoints:** https://bugs.spupgame.com/report, https://auth.spupgame.com ### 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 its crash reporter during startup., The reporter sends error messages, stack traces, build version, and the configured server URL to a fixed endpoint., Uncaught exceptions and unhandled rejections trigger reports; other server error paths also call the reporter. - **Evidence against:** The reporter targets the package vendor’s bug-report endpoint and reports server errors, consistent with crash telemetry., The package exports the server and test harness through explicit subpaths; the manifest has no lifecycle scripts. ## Affected versions and remediation This report applies to @spup/game-server@2.10.2. - Review the evidence and your use of @spup/game-server@2.10.2 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.
