{"cve":"CVE-2026-6404","nvd":{"published":"2026-05-20T02:16:38.357","modified":"2026-07-24T08:10:00.150","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","score":4.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/anomify/tags/0.3.6/Anomify/Config.php#L152","https://plugins.trac.wordpress.org/browser/anomify/tags/0.3.6/Anomify/Wp/Admin.php#L32","https://plugins.trac.wordpress.org/browser/anomify/tags/0.3.6/Anomify/Wp/includes/admin_options.php#L43","https://plugins.trac.wordpress.org/browser/anomify/trunk/Anomify/Config.php#L152","https://plugins.trac.wordpress.org/browser/anomify/trunk/Anomify/Wp/Admin.php#L32"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-6404","score":0.00239,"percentile":0.15039,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
