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 bundles contain an undisclosed remote data path with embedded service credentials, but it is activated only by explicit vectorKB configuration and does not establish malware behavior. Static hints about cloud metadata and execution are explained by bundled dependency code or safety checks. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-07T20:59:41.574Z - **Finished:** 2026-09-07T21:01:14.125Z - **Download time:** 519 ms - **Static scan time:** 7598 ms - **AI review time:** 84420 ms - **Total time:** 92551 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:** An enabled vector knowledge base can send user queries and supplied knowledge-base content to a package-selected remote Upstash service. The fallback service and its authorization token are embedded in the runtime bundle. - **Trigger:** A consumer enables vectorKB; uploads occur during chat when autoIngest is also enabled. - **Impact:** User prompts and configured knowledge-base content may be disclosed to a third-party endpoint without clear documentation. - **Evidence paths:** dist/index.js, dist/index.native.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T21:01:14.125Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote vector search and knowledge-base upload using embedded fallback credentials. - **Rationale:** The bundles contain an undisclosed remote data path with embedded service credentials, but it is activated only by explicit vectorKB configuration and does not establish malware behavior. Static hints about cloud metadata and execution are explained by bundled dependency code or safety checks. - **Network endpoints:** https://perfect-octopus-59684-us1-vector.upstash.io ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The published runtime entry point is dist/index.js., Both runtime bundles embed an Upstash endpoint and a bearer-style token as fallbacks for the vector knowledge base., When vector storage is enabled, searches send prompts remotely; automatic ingestion can upload knowledge-base questions, answers, and metadata during chat., The README does not disclose the vector-store fallback or automatic remote knowledge-base ingestion. - **Evidence against:** There is no install or postinstall hook; prepublishOnly only builds before publishing., The remote vector feature requires vectorKB.enabled, and automatic uploads additionally require autoIngest., The cloud-metadata strings are part of a URL-safety helper that rejects metadata endpoints, not an access attempt., No concrete shell execution, persistence, destructive action, or credential harvesting was found in the package-owned agent code. ## Affected versions and remediation This report applies to keyring-agent-core@0.3.5. - Review the evidence and your use of keyring-agent-core@0.3.5 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.
