Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The server exports telemetry to a third-party endpoint. During upstream HTTP errors, it attaches full client request, upstream request, and upstream response bodies to exported spans. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-29T19:10:12.247Z - **Finished:** 2026-09-29T19:11:42.069Z - **Download time:** 253 ms - **Static scan time:** 452 ms - **AI review time:** 89116 ms - **Total time:** 89822 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 server exports telemetry to a third-party endpoint. During upstream HTTP errors, it attaches full client request, upstream request, and upstream response bodies to exported spans. - **Trigger:** An upstream HTTP error while the CLI server handles a request. - **Impact:** Prompts, completions, and other request or response content may be disclosed to the telemetry recipient. - **Evidence paths:** dist/main.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-29T19:11:42.069Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Error handling captures raw bodies as span attributes, and the started telemetry provider exports traces, metrics, and logs to the default remote endpoint. - **Attack narrative:** When the user runs the package server, it starts a telemetry provider with a default third-party endpoint. If an upstream request fails, the active span is populated with the raw inbound body, outbound body, and upstream response. The provider exports these spans remotely. Header filtering does not prevent disclosure of sensitive content embedded in prompts or API payloads. - **Rationale:** The package has a concrete, active path that exports raw request and response content to a third-party telemetry service after upstream errors. This is data exfiltration behavior, not necessary proxy operation. - **Files touched:** dist/main.mjs - **Network endpoints:** https://api.honeycomb.io ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The executable entrypoint is dist/main.mjs., The runtime defaults its telemetry exporter to api.honeycomb.io., On upstream errors, it adds raw incoming request bodies, outgoing bodies, and upstream response bodies to telemetry spans., Those spans are exported to remote trace, metric, and log endpoints., The body-capture routine is invoked for HTTP error handling. - **Evidence against:** Sensitive header names are excluded from captured header fields, but request and response bodies are still captured. ## Affected versions and remediation This report applies to copilot-api-node20@0.43.0. - Avoid installing copilot-api-node20@0.43.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
