Auth bypass in Davidanderson Redux Framework

CVE-2026-103997

The Redux Framework plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.5.15. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to view the entire Redux options payload — including plaintext password field values, API keys, license keys, and SMTP credentials — exposed in the inline redux_<opt_name> JavaScript block on wp-admin/profile.php. The Users extension is loaded automatically for every Redux instance registered by any installed theme or plugin, meaning any site running Redux Framework is affected regardless of whether the developer explicitly configured the Users extension.
