Thu, 17 Sep 2026 15:32:45 +0000

Engineer — Plan: Any BIND server with DNS-over-HTTPS enabled can be crashed unauthenticated with a single malformed request; update to BIND 9.20.29 or 9.21.26 and audit whether DoH is exposed externally. No KEV listing or public PoC yet, but the zero-credential DoS lowers the exploitation bar significantly.
