This is a concrete credential disclosure surface, though no install-time behavior or local persistence was found. - **Trigger:** An authorized user opens /pvt/organization-account/buyer-organization-manager. - **Impact:** The remote agent origin receives a reusable auth token and associated account identifiers. - **Evidence paths:** package.json, plugin.config.js, src/pages/buyer-organization-manager.tsx, src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx - **Review source:** ai\_review - **Reviewed:** 2026-08-17T19:23:27.395Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cross-origin iframe postMessage of authentication and customer context - **Rationale:** The credential transfer to a hardcoded third-party-hosted receiver is real source behavior, but the inspected package does not establish malicious intent, stealth, install-time execution, or persistence. Treat it as an unresolved credential-exfiltration risk rather than a publish-blocking malware finding. - **Files touched:** package.json, plugin.config.js, src/pages/buyer-organization-manager.tsx, src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx - **Network endpoints:** https://buyer-bulk-ops-agent.vercel.app/app/buyer-bulk-ops-agent ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Hardcoded Vercel-hosted agent URL is loaded by the buyer-organization-manager route., The runtime posts the VTEX auth token and account/customer identifiers to that cross-origin iframe. - **Evidence against:** The page returns nothing unless its auth wrapper marks the request authorized., Messages are restricted to the configured iframe origin and iframe window., The only lifecycle hook is prepare: husky; no install/postinstall payload or shell execution was found. ## Public findings ### 1. Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Critical: Hardcoded Runtime Data Exfiltration - **Category:** Source - **Confidence:** 94.0% - **Path:** src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx - **Public source:** [View source]() Source sends credentials or rich application records to a package-controlled external receiver enabled by default.
