CVE-2026-6404

Anomify AI <= 0.3.6 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'anomify_api_key' Parameter

Published May 20, 2026 CVSS 3.1 · 4.4 Medium EPSS < 1% KEV · Not listed
Description
The Anomify AI – Anomaly Detection and Alerting plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'anomify_api_key' parameter in versions up to and including 0.3.6. This is due to insufficient input sanitization and missing output escaping: the plugin applies sanitize_text_field() to the Metric Data Key input before saving it via update_option(), but sanitize_text_field() strips HTML tags without encoding double-quote characters, and the value is then echoed directly into an HTML attribute context (value="...") without esc_attr(). This makes it possible for authenticated attackers with administrator-level access to inject arbitrary web scripts that execute whenever a user visits the plugin's settings page.
