WordPress Core 4.7.0 - 7.1.3 - Unauthenticated Upgrade-Window Staged-Installer Remote Code Execution

Published Oct 31, 2026 · Updated Nov 4, 2026 · Assigned by Wordfence

Vendor: WordPress Product: WordPress Package: wordpress Category: Web / CMS Ecosystem: Debian

Description

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.
