eve@0.66.3

Filesystem-first framework for durable backend AI agents that run anywhere.

AI Security Review

scanned 26d ago · by lpm-firewall-ai

Inspected package metadata and the required entry, auth, fixture, and Next server files show a user-run agent framework with no install hook or self-install chain. Vercel token refresh stays on allowlisted Vercel endpoints, and local process spawning is explicit developer behavior.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

No automatic install or import trigger starts the CLI, network auth, or local server.

Impact

No unconsented credential export, remote payload execution, or foreign agent-control write was established from the inspected entrypoints.

Mechanism

Lifecycle scripts are absent. The binary runs only when executed directly, OAuth hosts are allowlisted to Vercel, and the Next helper spawns a local eve process.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json declares eve 0.66.3 with bin and main entrypoints and only build, test, and typecheck scripts; no preinstall, install, or postinstall hook, and runtime dependencies are nitro and undici rather than eve itself.
bin/eve.js loads the compiled CLI only after confirming this file is the directly invoked process, so import of the package does not start the CLI.
Vercel model auth refreshes tokens only after checking OAuth endpoints belong to https://vercel.com or https://api.vercel.com.
mock-model-fixtures.js only builds local mock tool inputs and fixture tokens for agent tests.
http-basic.js compares a caller-supplied Basic username and password locally with a timing-safe hash and returns an authentication result.
The Next helper starts a local eve dev or production process in the app directory and records a loopback server origin.

Evidence against

The package implements user-invoked agent tools such as bash, file, and web access, which are the stated product behavior rather than an install-time attack.
OAuth and AI Gateway calls are bound to Vercel hosts and require an existing local session rather than a hidden third-party sink.
