# MAL-2026-4769: Malicious code in soundsource (PyPI)


- **Type:** Malicious package
- **Package:** `soundsource` (PyPI)
- **Published:** 19 May 2026

## What is MAL-2026-4769?

MAL-2026-4769 is a malicious package in soundsource, published on 19 May 2026. 

### Official description

The package's source distribution contains `Token.txt` at the tarball root holding a live PyPI API token (prefix `pypi-AgEIcHlwaS5vcmc...`). Anyone who downloads or installs the sdist obtains a credential granting publish rights on PyPI under the author's account, enabling republication of trojaned versions of this package (and any other package within the token's scope) to all downstream installers. Additional quality concerns include a malformed `Homepage` URL in `pyproject.toml` (`https://https://github.com/...`) and a placeholder `DEFAULT_BASE_URL` pointing at `api.soundsource.example.com`, indicating an unreviewed publish.

## What should I do about MAL-2026-4769?

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