CVE-2026-6404: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in simonholliday Anomify AI – Anomaly Detection and Alerting
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.
AI Analysis
Technical Summary
The Anomify AI plugin for WordPress suffers from a stored XSS vulnerability due to insufficient sanitization and escaping of the 'anomify_api_key' parameter. Although sanitize_text_field() is used, it does not encode double quotes, and the value is echoed directly into an HTML attribute without esc_attr(), enabling script injection by authenticated admin users. This vulnerability affects versions up to and including 0.3.6 and can lead to execution of arbitrary scripts in the context of the plugin's settings page.
Potential Impact
An authenticated attacker with administrator privileges can inject malicious scripts that execute in the browser of any user visiting the plugin's settings page. This can lead to information disclosure or other client-side impacts limited to the context of the affected page. The CVSS score of 4.4 reflects a medium severity with low confidentiality and integrity impact and no availability impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. 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.
