AI Security Review

scanned 23d ago · by lpm-firewall-ai

No confirmed malicious attack surface. When a consumer explicitly invokes the deployer, it creates Vercel deployment output and optionally copies bundled Studio assets.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

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.

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.

AI called this Clean at 98.0% confidence as Benign with low false-positive risk.

Evidence for block

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.
