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. Both authenticated page flows send VTEX session credentials to fixed external agent origins without a recipient-specific approval gate. The source establishes the transfer but not recipient ownership or subsequent credential use, so warn about credential exposure without asserting malicious use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-22T14:05:06.732Z - **Finished:** 2026-10-22T14:06:03.890Z - **Download time:** 1027 ms - **Static scan time:** 935 ms - **AI review time:** 55195 ms - **Total time:** 57158 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:** Authenticated pages forward VTEX session tokens to fixed external agent apps. The source does not establish whether those recipients are authorized to receive or use the tokens, so the credential exposure remains unresolved. - **Trigger:** An authorized user opens the buyer organization manager or order-entry page and its embedded iframe loads. - **Impact:** The remote recipient receives session credentials that may allow actions under the user's account; source does not show subsequent use. - **Evidence paths:** src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx, src/pages/buyer-organization-manager.tsx, src/features/order-entry/layouts/OrderEntryLayout.tsx, src/pages/order-entry.tsx - **Review source:** ai\_review - **Reviewed:** 2026-10-22T14:06:03.890Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The layouts send auth tokens and related account or session data to fixed Vercel origins through postMessage, after a readiness message or iframe load. - **Rationale:** Both authenticated page flows send VTEX session credentials to fixed external agent origins without a recipient-specific approval gate. The source establishes the transfer but not recipient ownership or subsequent credential use, so warn about credential exposure without asserting malicious use. - **Files touched:** src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx, src/pages/buyer-organization-manager.tsx, src/features/order-entry/layouts/OrderEntryLayout.tsx, src/pages/order-entry.tsx - **Network endpoints:** buyer-bulk-ops-agent.vercel.app, order-entry-agent.vercel.app ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The B2B manager embeds a fixed external agent origin., The B2B layout sends the VTEX auth token and account details to that origin., The authorized B2B page derives the token from session context or cookies and passes it to the layout., The order-entry layout uses a second fixed external agent origin and sends both auth token fields plus session context., The authorized order-entry page derives the token and passes it to the layout., Both layouts send authentication automatically after the iframe loads; no recipient-specific approval is shown. - **Evidence against:** Outbound messages are constrained to the iframe origin, and inbound messages are checked against that origin and window. The source does not establish how the remote apps use the credentials. ## Affected versions and remediation This report applies to @vtex/faststore-plugin-buyer-portal@2.0.40. - Review the evidence and your use of @vtex/faststore-plugin-buyer-portal@2.0.40 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.
