Running Go? Upgrade to 1.27.3 or 1.26.10.
Rust with rustls? Upgrade to rustls-webpki 0.103.16 and/or webpki-roots/webpki-root-certs 1.0.10.
Python? Upgrade certifi to 2026.10.19.
Homebrew ca-certificates? 2026-09-25_1.
Electron? 44.9.1, 43.8.1, or 42.11.16.
The Go and Rustls upgrades specifically block the intermediate certs because neither of these use the system revocation lists, I believe. Once you upgrade to a trust store without the root cert for the CA this will also solve the issue. Not sure about other ecosystems.
