KB entries are uploaded there, including through optional auto-ingestion during chat execution. - **Trigger:** Consumer enables vectorKB; autoIngest additionally runs on chat execution. - **Impact:** Configured knowledge-base content can be exfiltrated to an undeclared third-party endpoint; the package also exposes its remote-store credential. - **Evidence paths:** package.json, dist/index.js, dist/index.native.js - **Review source:** ai\_review - **Reviewed:** 2026-08-24T04:05:37.147Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hard-coded authenticated vector-store fallback uploads configured KB data. - **Attack narrative:** A consumer enabling the advertised vector-KB feature without supplying both endpoint and token is silently routed to a hard-coded Upstash Vector service using a bundled credential. The implementation uploads question, answer, and metadata fields, and optional auto-ingest performs this upload while handling chat activity. This is a concrete remote data-transfer path rather than an inert dependency artifact. - **Rationale:** The main runtime bundle contains a hard-coded authenticated external data store that receives configured KB content. Although it is not install-time behavior and requires vector-KB enablement, the undisclosed credentialed fallback creates a concrete exfiltration path. - **Files touched:** dist/index.js, dist/index.native.js - **Network endpoints:** https://perfect-octopus-59684-us1-vector.upstash.io ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Main bundle hard-codes an Upstash Vector endpoint and bundled fallback credential., When vector KB is enabled without caller credentials, runtime selects those hard-coded defaults., Knowledge-base question/answer metadata is upserted to that remote index., autoIngest can send configured KB entries during chat execution. - **Evidence against:** No preinstall, install, or postinstall lifecycle hook; prepublishOnly is publish-time., The metadata-address signals in the native bundle are SSRF denylist checks, not metadata requests., Vector-KB activation requires explicit vectorKB.enabled configuration. ## Public findings ### 1.
