  • Eight eMudhra intermediate CA keys leaked on 2026-10-20 (https://bugzilla.mozilla.org/show_bug.cgi?id=2083449)
  • Anyone holding them can mint a TLS cert for any host, so outbound calls can be intercepted
  • The Lambda base is Amazon Linux 2023, which has no ca-certificates release without emSign ECC Root CA - G3 yet
  • Blocklist that root with p11-kit and keep upgrading ca-certificates so the AL2023 fix lands on rebuild
