When a consumer explicitly invokes the deployer, it creates Vercel deployment output and optionally copies bundled Studio assets. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 98.0% - **Started:** 2026-07-28T23:15:56.509Z - **Finished:** 2026-07-28T23:16:36.967Z - **Download time:** 506 ms - **Static scan time:** 1348 ms - **AI review time:** 38604 ms - **Total time:** 40458 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. When a consumer explicitly invokes the deployer, it creates Vercel deployment output and optionally copies bundled Studio assets. - **Trigger:** Consumer invokes VercelDeployer prepare or bundle during an application deployment. - **Impact:** Writes scoped deployment artifacts in the consumer project; no unconsented install-time action or exfiltration was found. - **Evidence paths:** package.json, dist/index.js, dist/index.cjs, dist/index.js.map, dist/studio/index.html, dist/studio/assets/index-sToavS1V.js, dist/studio/assets/tsx-B6W0miNI.js - **Review source:** ai\_review - **Reviewed:** 2026-07-28T23:16:36.967Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Generate Vercel function configuration and optional same-origin Studio files. - **Rationale:** The package is a user-invoked Vercel deployer with scoped deployment-file writes and an optional bundled Studio UI. Scanner signals stem from legitimate deployment behavior and bundled browser/grammar assets, not a concrete malicious chain. - **Files touched:** .vercel/output/config.json, .vercel/output/functions/index.func/.vc-config.json, .vercel/output/static/index.html ### Review decision - **Verdict:** Clean - **Confidence:** 98.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** package.json has no lifecycle hooks or bin entrypoint., dist/index.js only exports VercelDeployer; no import-time deployment action., Project writes occur only in explicit prepare/bundle methods., Environment values are escaped before Studio HTML injection., No credential harvesting, child-process execution, eval, or remote payload loading found., Studio assets use same-origin API/SSE paths; bundled grammar files explain dynamic-require signal. ## Public findings ### 1.
