Critical WordPress Vulnerability Exposed

A significant vulnerability in WordPress, designated as CVE-2026-119977, poses the risk of remote code execution during the software’s update process. This flaw is found in versions ranging from 4.7 to 7.1.3 of the platform.

According to Coin Bureau, WordPress underpins 39.5% of all websites globally. This vulnerability raises alarms as it may allow malicious actors to execute arbitrary code directly on the server during a full update, thereby compromising site integrity.

Mechanics of the Vulnerability

The WordPress update mechanism temporarily places its installer in a publicly accessible folder, creating a narrow window for exploitation. As reported by Coin Bureau, an attacker who gains access to this folder during the update can execute their own code, navigating around authentication protocols.

This vulnerability necessitates no authentication, rendering it particularly perilous. The threat lies in the temporary exposure, granting unauthorized individuals potential control over the affected website.

All iterations of WordPress from version 4.7 to 7.1.3 are implicated, encompassing nearly a decade of updates since December 2016, thereby affecting a vast array of deployments.
