CVE-2026-110534: Redux Framework <= 4.5.16 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Color Scheme Name

Q: Which sites are actually exposed to subscriber-level exploitation?

A site is exposed in this way only if its active theme registers a color_scheme field on the user profile through Redux_Users::set_profile(). That condition renders the required nonce on /wp-admin/profile.php for every logged-in user, including Subscribers.

Q: What access does an attacker need?

The attacker must be authenticated with at least Subscriber-level access. They can inject script through the affected content parameter, and the script executes when someone visits the injected page.

Q: Are unauthenticated visitors able to exploit this issue?

The provided information describes exploitation by authenticated users only. It specifically requires access to the logged-in profile page nonce under the affected theme configuration.

Updated

The Redux Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content' parameter in all versions up to, and including, 4.5.16 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 requires the target site's theme to register a colorscheme field on the user profile via ReduxUsers::setprofile(), which causes the nonce to be rendered on /wp-admin/profile.php for every logged-in user, making it accessible to Subscribers.
