WordPress core upgrade race condition draws mass exploit attempts
First merged summary.
Attackers are probing CVE-2026-119977 in WordPress 4.7–7.1.3; patches exist, but sites can stay exposed while updating.
Wordfence recorded more than 240,000 blocked exploit attempts against CVE-2026-119977, a WordPress Core race condition that can allow unauthenticated remote code execution during a full upgrade. The flaw affects unpatched branches 4.7 through 7.1.3 and is fixed in 7.1.4 and matching backports. Cyber Security News says the counts are blocked requests, not confirmed infections, and that success is difficult because of the timing window. The Hacker News reports active exploitation, including a CISA KEV listing, and says installing the fix can still use old code and leave a last exposure window. WordPress 7.1.4 randomizes staging directories and adds an index guard.
