CVE-2026-88999
The Redux Framework plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.5.14 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 delete arbitrary media library attachments, including administrator-owned files, from the affected site. This is exploitable by Subscribers when a Custom Fonts field is registered on the user profile page via Redux_Users::set_profile(), as doing so causes the required redux_custom_fonts nonce to be rendered into the Subscriber's wp-admin/profile.php page.
