This creates a privacy and shared-credential risk, not an install-time attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-09T02:56:30.321Z - **Finished:** 2026-08-09T02:57:31.840Z - **Download time:** 520 ms - **Static scan time:** 5131 ms - **AI review time:** 55867 ms - **Total time:** 61519 ms ## Security analysis ### Published attack-surface review - **Summary:** An opt-in vector-KB feature can use a package-embedded third-party Upstash endpoint and credential when caller configuration/env values are absent. This creates a privacy and shared-credential risk, not an install-time attack. - **Trigger:** Consumer enables vectorKB; uploads additionally require autoIngest: true or an explicit ingest call. - **Impact:** Configured knowledge-base content and queries may be sent to the embedded Upstash backend. - **Evidence paths:** package.json, dist/index.js, dist/index.native.js, dist/index.d.ts, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T02:57:31.840Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** opt-in remote vector-store query and ingestion - **Rationale:** No concrete malware chain, hidden execution, or install-time mutation was found. Warn because an opt-in data feature defaults to a package-controlled remote vector store using an embedded credential. - **Files touched:** dist/index.js - **Network endpoints:** https://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:** dist/index.js embeds an Upstash Vector REST URL and token as fallbacks., When vectorKB.enabled is set, AgentCore instantiates that backend; queries transmit KB search text., autoIngest can upload configured knowledge-base question/answer entries to the fallback backend. - **Evidence against:** package.json has only prepublishOnly; no install-time lifecycle hook., No child\_process, eval, Function, or VM execution found in either distribution entrypoint., Cloud-metadata strings occur in bundled dependency SSRF-protection code, not package requests., Vector KB is opt-in and auto-ingestion requires autoIngest: true. ## Public findings ### 1.
