Cross-Site Request Forgery in Wp Js Detect WordPress Plugin

Publication date: 2026-07-08

Last updated on: 2026-07-08

Assigner: Wordfence

Description
The Wp Js Detect plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.9. This is due to missing or incorrect nonce validation on the plugin_settings function. This makes it possible for unauthenticated attackers to update the plugin's notification text and CSS settings (wp_non_js_notification_text and wp_non_js_notification_css), injecting arbitrary content that is echoed unescaped on the frontend via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Executive Summary

The Wp Js Detect plugin for WordPress has a Cross-Site Request Forgery (CSRF) vulnerability in all versions up to and including 1.0.9. This occurs because the plugin's settings function lacks proper nonce validation, which is a security measure to verify legitimate requests.

As a result, an attacker who is not authenticated can trick a site administrator into performing an action, such as clicking a malicious link, which allows the attacker to update the plugin's notification text and CSS settings. The injected content is then displayed unescaped on the frontend, potentially allowing arbitrary content injection.

Impact Analysis

This vulnerability can impact you by allowing an attacker to inject arbitrary content into your website's frontend through the plugin's notification text and CSS settings. Since the content is echoed unescaped, it could lead to content manipulation or defacement.

Although the vulnerability does not directly compromise confidentiality or availability, it can affect the integrity of your website's content and potentially harm your site's reputation or user trust.
