{"cve":"CVE-2026-90992","nvd":{"published":"2026-10-01T09:17:09.927","modified":"2026-10-01T19:17:25.497","status":"Deferred","description":"The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via User Meta Merge via 'user-mediaurl' Media Field in all versions up to, and including, 4.5.14 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by Subscriber-level users who can store a payload in user meta fields such as the biography, session_tokens (via a crafted User-Agent at login), or persisted_preferences (via the REST API), which are then promoted to the site-wide redux_demo option when a media URL repair is triggered on the demo panel.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/redux-framework/tags/4.5.14/redux-core/assets/js/vendor/jsonview.js#L136","https://plugins.trac.wordpress.org/browser/redux-framework/tags/4.5.14/redux-core/inc/classes/class-redux-options-constructor.php#L189","https://plugins.trac.wordpress.org/browser/redux-framework/tags/4.5.14/redux-core/inc/classes/class-redux-options-constructor.php#L632","https://plugins.trac.wordpress.org/browser/redux-framework/tags/4.5.14/redux-core/inc/extensions/users/class-redux-extension-users.php#L365","https://plugins.trac.wordpress.org/browser/redux-framework/tags/4.5.14/redux-core/inc/extensions/users/class-redux-users-api.php#L558"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-90992","score":0.00235,"percentile":0.14366,"date":"2026-10-25"},"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).
