CVE-2026-90992

Redux Framework <= 4.5.14 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'user-mediaurl' Media Field

Published Oct 1, 2026 CVSS 3.1 · 6.4 Medium EPSS < 1% KEV · Not listed
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.
