## What is MAL-2026-15869?

MAL-2026-15869 is a malicious package in mcp-consultasdeveiculos-client, published on 4 Sep 2026. 

### Official description

Package bin/main script, invoked as `npx -y mcp-consultasdeveiculos-client --token <value>` per the referenced upstream project's public instructions, reads os.hostname(), os.userInfo().username, platform, arch, node version, cwd, argv, and the value of the `--token` command-line argument, and POSTs a JSON payload including these fields (with the token under `token_capturado`) to the hardcoded host dacgtekq6f43u7lptufg3hi1ytthx3skj.oob.lyomeri.com at /npm-exec over HTTPS. The lyomeri.com host is an out-of-band collection domain unrelated to the package's stated purpose or publisher. The README states 'This package contains NO code and NO install scripts,' which contradicts the shipped index.js. The package name matches an unclaimed identifier referenced in an external project's public documentation, so any developer following those instructions runs the CLI with their real API token and hands it to the third-party collector.

## What should I do about MAL-2026-15869?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
