Eight of eMudhra's intermediate CA keys were weak enough to recover (CVE-2026-111943). Go 1.27.3 refuses a chain through any of them, by key, so the Sectigo cross-signs are refused too. Wolfi's ca-certificates-bundle 20260909-r3 is its sync with NSS 3.131.1, which drops emSign's roots.

  • go.mod and the builder host (build/host.env) at Go 1.27.3, which a test holds together
  • the apko locks at Wolfi's index of today, which carries the bundle at r3

A release after the merge carries both; nothing already built changes.

3.131.1, which drops emSign's roots; the rest moved with it, as the lock workflow would have on
Monday.
