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. This is a warning-level telemetry concern: sampled error events include raw stack traces that can reveal local paths and are sent to the configured intake. The behavior requires an explicit SDK \`init\` call and can be disabled with a zero telemetry sample rate, so it is suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-11-03T19:41:43.827Z - **Finished:** 2026-11-03T19:42:53.647Z - **Download time:** 763 ms - **Static scan time:** 3629 ms - **AI review time:** 65426 ms - **Total time:** 69820 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:** Sampled runtime error telemetry may disclose local paths in stack traces to the FlashCat RUM intake. - **Trigger:** The application calls \`init\`; telemetry is enabled by default at a 20% sample rate. - **Impact:** Error details and local filesystem paths may be disclosed to the configured service. - **Evidence paths:** dist/index.cjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-03T19:42:53.647Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK formats internal errors with their message and stack, then sends event batches to the configured intake. - **Rationale:** This is a warning-level telemetry concern: sampled error events include raw stack traces that can reveal local paths and are sent to the configured intake. The behavior requires an explicit SDK \`init\` call and can be disabled with a zero telemetry sample rate, so it is suspicious rather than malicious. - **Network endpoints:** https://{configured site}/api/v2/rum (default host: browser.flashcat.cloud) ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** After \`init\`, the SDK enables error telemetry by default; the README lists a 20% default sample rate., Telemetry error events include error messages and raw stack traces, which can contain local paths., The SDK posts collected events to its configured RUM intake using the supplied client token., Telemetry starts only when the application calls the SDK’s \`init\` function. - **Evidence against:** The README identifies the feature as telemetry and exposes \`telemetrySampleRate\` to control it., The upload destination is the configured intake host; the README documents FlashCat’s default host., A separate \`instrument\` entry disables dd-trace’s own instrumentation telemetry by default., The manifest’s \`prepare\` script runs Husky; no package install hook sending data was identified. ## Affected versions and remediation This report applies to @flashcatcloud/electron-sdk@0.4.0. - Review the evidence and your use of @flashcatcloud/electron-sdk@0.4.0 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.
