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 includes runtime telemetry in the bundled Cursor SDK, which is sent to Cursor's own service when SDK operations run. I found no disclosure or opt-out in the inspected path, so this warrants a warning rather than a block; the source does not show unrelated credential exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-11-01T07:56:25.388Z - **Finished:** 2026-11-01T08:02:21.583Z - **Download time:** 54379 ms - **Static scan time:** 46173 ms - **AI review time:** 255642 ms - **Total time:** 356195 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:** The bundled Cursor SDK sends runtime usage telemetry to Cursor's backend. - **Trigger:** When SDK operations occur and a Cursor API key is available. - **Impact:** Cursor receives SDK usage and error details. The reviewed flow does not show credentials being sent to a foreign service. - **Evidence paths:** node\_modules/@cursor/sdk/dist/esm/index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T08:02:21.583Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It queues SDK events and flushes them to \`api2.cursor.sh\`, including runtime and operation metadata; no consent check or opt-out was evident in the inspected path. - **Rationale:** The package includes runtime telemetry in the bundled Cursor SDK, which is sent to Cursor's own service when SDK operations run. I found no disclosure or opt-out in the inspected path, so this warrants a warning rather than a block; the source does not show unrelated credential exfiltration. - **Network endpoints:** api2.cursor.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest describes a platform-specific s2code CLI package that ships the \`t3\` executable and client files., The bundled Cursor SDK creates a telemetry client targeting \`api2.cursor.sh\` and attaches SDK version and platform fields to events., The SDK queues telemetry events and schedules flushes at a three-second interval., The SDK records run creation and completion, executor startup, pull request opening, and operation error details., The SDK resolves its key from an explicit argument, \`CURSOR\_API\_KEY\`, or its credential store; the inspected telemetry client sends to Cursor's own backend. - **Evidence against:** The manifest has no lifecycle scripts, so the inspected telemetry is not triggered by installation., The flagged setup commands name the official Claude and ChatGPT install hosts., The inspected GitHub release helper attaches a GitHub token only when the request host is \`github.com\`., No source reviewed shows credentials being sent to an unrelated host or an account action performed toward a publisher-selected target. ## Affected versions and remediation This report applies to @s2code/t3-linux-arm64@0.1.5-nightly.20261101.76. - Review the evidence and your use of @s2code/t3-linux-arm64@0.1.5-nightly.20261101.76 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.
