Until a fix is available, restrict administrator access to trusted users only and avoid visiting the plugin's settings page unnecessarily. Monitor for updates from the vendor regarding patches or official fixes.
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.
