# MAL-2026-5582: Malicious code in wp-env (npm)


- **Type:** Malicious package
- **Package:** `wp-env` (npm)
- **Published:** 11 Jun 2026

## What is MAL-2026-5582?

MAL-2026-5582 is a malicious package in wp-env, published on 11 Jun 2026. 

### Official description

Package squats the `wp-env` CLI name commonly invoked as `npx wp-env` by users intending @wordpress/env. The package ships only `bin/run.js` (declared `main: index.js` is absent from the tarball), so its sole execution surface is the bin script that fires when a developer runs `npx wp-env`. On execution, bin/run.js reads `process.env.INIT_CWD`, derives the basename of the installer's project directory, and POSTs it together with timestamp and package metadata to a hardcoded callback URL `https://deepbounty.dd06-dev.fr/cb/dc43de99-70fc-4782-8668-bec6eee1975b`. The package self-describes as a 'Security PoC for Bug Bounty' — name-confusion attack against @wordpress/env combined with concrete installer-side data exfiltration (the project directory basename, sent to an attacker-controlled host that uses a per-target callback path to identify successfully-confused victims). This satisfies both the typosquat shape (≤2 char edit / namespace confusion vs. @wordpress/env's `wp-env` CLI) and a concrete exfil payload to an attacker-controlled destination.

## What should I do about MAL-2026-5582?
