WordPress core CVE-2026-119977: unauthenticated code execution during core upgrades, added to KEV (due 6 Nov)
Added on 3 Nov. A time-of-check time-of-use race condition could let unauthenticated attackers execute code on the server during the upgrade window, because full-package core upgrades use predictable, web-accessible staging paths. The federal due date is 6 Nov, which is today. Check that your sites are on the fixed WordPress release and look at your auto-update status.
