XSS in Davidanderson Redux Framework

CVE-2026-110534

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 color_scheme field on the user profile via Redux_Users::set_profile(), which causes the nonce to be rendered on /wp-admin/profile.php for every logged-in user, making it accessible to Subscribers.
