CVE-2026-14289

A flaw in the FacturaONE para WooCommerce plugin for WordPress allows attackers to write files to the web server without authentication. Because the plugin’s request handler is not protected, an attacker can upload malicious code and run it on the site. The vulnerability is critical and can be exploited remotely.

01

Who is affected

WordPress sites that use the FacturaONE para WooCommerce plugin with VeriFactu before version 5.37. Site owners who have not upgraded the plugin are at risk.

02

Real-world impact

An attacker can place any file, such as a web shell, into a publicly accessible folder and then execute it, giving full control over the affected WordPress site.

03

Why this severity

The CVSS score of 9 reflects that the flaw can be exploited over the network, requires no user interaction, and gives the attacker full confidentiality, integrity, and availability compromise. The attack complexity is high because the plugin’s default configuration leaves a cryptographic key empty, but once that condition is met the attacker can execute arbitrary code.

04

What to do about it

no official fix yet
