It has since been removed through the bundle and the new version no longer includes them.\n\n[pypi-publish]: https://github.com/marketplace/actions/pypi-publish\n\n### Details\n\nThe `certifi`-provided TLS trust store is typically used by many projects in the Python ecosystem, including Sigstore that [pypi-publish] relies on for Trusted Publishing and Digital Attestations.\n\n### Related\n\nThe external compromise is being tracked at https://emudhra.we-have-a-problem.com",
