What the vulnerability does

01Description

The Anomify AI – Anomaly Detection and Alerting plugin for WordPress is vulnerable to Cross-Site Request Forgery (CSRF) leading to Stored Cross-Site Scripting (XSS) in versions up to and including 0.3.6. This is due to missing nonce verification on the settings page handler and insufficient output escaping in the admin_options.php template. The settings form includes no wp_nonce_field() and the handler performs no check_admin_referer() check, meaning any cross-origin POST can modify plugin settings. The API key field is sanitized only with sanitize_text_field(), which strips HTML tags but does not encode double-quote characters; the value is then rendered into an HTML attribute via bare echo without esc_attr(), allowing a double-quote attribute-escape payload to survive both sanitization and storage. This makes it possible for unauthenticated attackers to inject arbitrary web scripts by tricking a logged-in administrator into visiting a malicious page that submits a forged request, storing the payload in the database and causing it to execute in the administrator's browser whenever the plugin settings page is visited.

Explanation of Vulnerability in Simple Terms

02Summary

Anomify AI versions 0.3.6 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in user, performs unwanted actions on their behalf within the application. The vulnerability requires user interaction—the victim must visit the attacker's page while authenticated. Integrity of data or settings may be compromised.

What an attacker can do

03Attacker Capabilities
