Redux Framework plugin lets logged‑in users run scripts

CVE-2026-90992 · published 1 month ago
Summary

The Redux Framework plugin for WordPress (up to version 4.5.14) does not properly clean certain input fields. As a result, a user with a basic account can add malicious code that runs whenever anyone views the affected page. Update the plugin to the latest version or remove it if you cannot apply the update.

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.
