Vulnerability Title
Redux Framework <= 4.5.14 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Attachment Deletion via 'attachment_id' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
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.
