{"id":"CVE-2026-6404","state":"PUBLISHED","title":"Anomify AI <= 0.3.6 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'anomify_api_key' Parameter","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.","publishedAt":"2026-05-20T01:25:48.238Z","updatedAt":"2026-05-20T14:02:41.130Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["simonholliday Anomify AI – Anomaly Detection and Alerting"],"affected":[{"vendor":"simonholliday","product":"Anomify AI – Anomaly Detection and Alerting","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.3.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4036057c-0c43-4d9c-97db-4861d91a4daa?source=cve","https://plugins.trac.wordpress.org/browser/anomify/trunk/Anomify/Wp/includes/admin_options.php#L43","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/Wp/Admin.php#L32","https://plugins.trac.wordpress.org/browser/anomify/tags/0.3.6/Anomify/Wp/Admin.php#L32","https://plugins.trac.wordpress.org/browser/anomify/trunk/Anomify/Config.php#L152","https://plugins.trac.wordpress.org/browser/anomify/tags/0.3.6/Anomify/Config.php#L152"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6404.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6404","state":"PUBLISHED","datePublished":"2026-05-20T01:25:48.238Z","dateUpdated":"2026-05-20T14:02:41.130Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-15T20:41:22.682Z"},"containers":{"cna":{"title":"Anomify AI <= 0.3.6 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'anomify_api_key' Parameter","descriptions":[{"lang":"en","value":"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.
