Vulnerability from github – Published: 2026-10-31 06:30 – Updated: 2026-10-31 06:30

Details

WordPress Core is vulnerable to Remote Code Execution in versions 4.7 through 7.1.3. This is due to predictable, web-accessible staging paths used during full-package core upgrades. This makes it possible for unauthenticated attackers to execute code on the server during the upgrade window.

Severity

8.1 (High)
