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 real remote-upload capability with a hard-coded destination, but it is activated only through an explicit vectorKB and autoIngest configuration. There is no install-time execution or confirmed arbitrary payload execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-12T14:13:01.118Z - **Finished:** 2026-09-12T14:15:23.957Z - **Download time:** 515 ms - **Static scan time:** 4076 ms - **AI review time:** 138247 ms - **Total time:** 142839 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 supplied knowledge-base content to a hard-coded external Upstash Vector endpoint. Automatic upload requires the caller to enable both the vector store and automatic ingestion. - **Trigger:** A consumer creates AgentCore with vectorKB enabled and autoIngest true, then uses chat. - **Impact:** Knowledge-base content may be disclosed to a service chosen by the package rather than the consumer. - **Evidence paths:** dist/index.js, dist/index.native.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T14:15:23.957Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic vector-store upload to a hard-coded remote service. - **Rationale:** This is a real remote-upload capability with a hard-coded destination, but it is activated only through an explicit vectorKB and autoIngest configuration. There is no install-time execution or confirmed arbitrary payload execution. - **Network endpoints:** perfect-octopus-59684-us1-vector.upstash.io ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The native build hard-codes an Upstash Vector service endpoint instead of requiring a caller-supplied endpoint., When enabled, the vector knowledge-base feature uploads configured knowledge-base entries to that service, including through automatic ingestion., The Node build contains the same automatic-ingestion path, so the behavior is not limited to the native artifact. - **Evidence against:** package.json has only a prepublish build hook; it has no install-time lifecycle hook., The upload path is gated by the caller enabling vectorKB and autoIngest., No shell execution, dynamic code evaluation, or filesystem harvesting was found in the inspected entry builds. ## Affected versions and remediation This report applies to keyring-agent-core@0.3.8. - Review the evidence and your use of keyring-agent-core@0.3.8 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.
