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.
