certifi 2026.10.19 removes the emSign roots after the eMudhra intermediate CA compromise (certifi/python-certifi#437, #440). The pin in `tools/requirements.txt` is still on 2026.7.22, which trusts those roots. Since `tools/pip_install.py` uses this file as the pip constraint, the published `certbot/certbot` and `certbot/dns-*` Docker images ship the old bundle, and ACME requests made through `requests` still accept chains issued by the compromised intermediates. This only bumps the certifi line. Happy to run a full repin with `tools/pinning/current/repin.sh` instead if you prefer. How to check: inside the current `certbot/certbot:latest` image, `python -c "import certifi; print(certifi.__version__)"` prints 2026.07.22, and a TLS connection to `dv-g3b-emudhra.we-have-a-problem.com` (a test site served by one of the affected intermediates) verifies against `certifi.where()`.
