This is a credential-exposure and query-privacy risk, not confirmed malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-08-20T10:21:11.838Z - **Finished:** 2026-08-20T10:22:55.149Z - **Download time:** 506 ms - **Static scan time:** 7585 ms - **AI review time:** 95219 ms - **Total time:** 103311 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicitly enabled vector knowledge-base feature submits runtime queries to a package-controlled Upstash endpoint using embedded fallback credentials. This is a credential-exposure and query-privacy risk, not confirmed malware. - **Trigger:** Consumer enables AgentCore vectorKB without supplying its own provider. - **Impact:** Third parties can misuse the exposed service credential; enabled users' query text may be sent to the endpoint. - **Evidence paths:** package.json, dist/index.js, dist/index.native.js, dist/index.d.ts, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-20T10:22:55.149Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Queries a hard-coded Upstash Vector account with embedded fallback credentials. - **Rationale:** The embedded service credential is a concrete security defect with runtime data-flow implications, warranting a warning. The code path is opt-in and no concrete malicious execution chain was found. - **Network endpoints:** https://perfect-octopus-59684-us1-vector.upstash.io ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** Bundled Upstash KB client contains package-supplied fallback URL and token values instead of requiring caller credentials., When vectorKB is enabled, AgentCore searches it with the user's query; the embedded account can therefore receive query data., The hard-coded credential is an exposed service credential and enables unauthorized use of the package owner's vector service. - **Evidence against:** No preinstall, install, or postinstall hook; prepublishOnly only runs the build., Vector KB network use is gated by explicit vectorKB.enabled configuration., No child-process, eval-based payload execution, filesystem harvesting, or AI-agent configuration mutation was found in inspected entrypoints., Cloud-metadata strings in the native bundle are URL-safety denylist data, not metadata requests. ## Public findings ### 1.
