 "title": "Redux Framework <= 4.5.15 - Authenticated (Subscriber+) Missing Authorization to Restricted Profile Field Update via 'checkuser_id' Parameter",
 "description": "The Redux Framework plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.5.15 due to the user profile field save routine checking field-level permissions against a user ID taken from the client-supplied 'checkuser_id' parameter instead of the current user. This makes it possible for authenticated attackers with Subscriber-level access and above to supply an administrator's user ID and save values to permission-restricted Redux profile fields that they should not be able to modify.",
