Visiting either authenticated agent route loads a remote Vercel iframe and sends VTEX authentication/session data to it. This is a concrete credential delegation boundary, but not install-time execution.

## Security analysis

### Published attack-surface review

- **Summary:** Visiting either authenticated agent route loads a remote Vercel iframe and sends VTEX authentication/session data to it. This is a concrete credential delegation boundary, but not install-time execution.

- **Trigger:** An authenticated user opens buyer-organization-manager or order-entry.

- **Impact:** The remote agent services can receive reusable VTEX credentials and related account/session data.

- **Evidence paths:** package.json, .husky/pre-commit, src/pages/buyer-organization-manager.tsx, src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx, src/features/order-entry/layouts/OrderEntryLayout.tsx, docs/scope\_of\_work/organization-self-management.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T12:35:15.170Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Cross-origin iframe postMessage of authentication and user context.

- **Rationale:** Source inspection does not support the scanner’s malicious install-hook claim. It does show deliberate runtime transfer of credentials to fixed third-party-hosted agent endpoints, warranting a warning pending trust/ownership validation.

- **Files touched:** package.json, .husky/pre-commit, beta-release.sh, src/pages/buyer-organization-manager.tsx, src/features/b2b-agent/layouts/B2BAgentLayout/B2BAgentLayout.tsx, src/features/order-entry/layouts/OrderEntryLayout.tsx, docs/scope\_of\_work/organization-self-management.md

- **Network endpoints:** https://buyer-bulk-ops-agent.vercel.app/app/buyer-bulk-ops-agent, https://order-entry-agent.vercel.app/app/order-entry-agent

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 87.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for:** Authenticated routes extract VTEX auth-cookie values., Two default remote Vercel iframes receive auth/session context via postMessage., Remote iframe hosts are separate from the storefront origin.

- **Evidence against:** package.json has only prepare: husky; no preinstall/install/postinstall., Husky hook only runs lint-staged on developer pre-commit., Routes require authorization and explicitly implement the agent UI., postMessage checks both expected origin and iframe window., No child-process, eval, file harvesting, or install-time network behavior found.
