At a glance
CVE-2026-14204 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Google Authenticator WordPress plugin, affecting versions <= 0.55. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 0.56; sites on affected versions should update now. Disclosed August 2026, reported by Miguel Mendez Z.
Vulnerability Overview
The Google Authenticator plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 0.55. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Google Authenticator <= 0.55 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Google Authenticator the fix is 0.56: builds <= 0.55 are affected, anything from 0.56 onward is not.
Remediation
Update to version 0.56, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Google Authenticator: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Google Authenticator 0.56 closes this, and updating the plugin is the step that ends it.
