## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. The package provides an explicitly invoked Vercel deployment adapter that writes deployment artifacts into the caller’s project.

- **Trigger:** User configures and invokes VercelDeployer during a Mastra build/deployment.

- **Impact:** Creates .vercel/output artifacts and a same-origin Studio configuration; no install-time execution, exfiltration, or persistence found.

- **Evidence paths:** package.json, dist/index.js, dist/index.cjs, dist/studio/index.html, dist/studio/assets/tsx-B6W0miNI.js, dist/studio/assets/livekit-client.esm-CKIgC2IJ.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-26T19:11:07.268Z

### AI review details

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

- **Mechanism:** Generate Vercel function routes/configuration and optionally copy Studio static assets.

- **Rationale:** Direct inspection found no lifecycle hook or concrete malicious chain. File and environment handling is aligned with the documented, user-invoked Vercel deployment function.

- **Files touched:** .vercel/output/functions/index.func/.vc-config.json, .vercel/output/config.json, .vercel/output/static/index.html

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no preinstall/install/postinstall hooks., dist/index.js only runs deployment actions through VercelDeployer methods., Writes are limited to user deployment output: .vercel/output config and optional copied Studio assets., Environment values are HTML-escaped before insertion; no external endpoint is set by this deployer., Flagged dynamic/eval patterns are inside bundled Studio/editor and LiveKit browser assets, not package install code.
