CVE-2023-47191 is a medium-severity Authorization Bypass Through User-Controlled Key vulnerability in the Youzify WordPress plugin, affecting versions <= 1.2.2.

Disclosed November 2023, reported by lttn.

Vulnerability Overview

The Youzify – BuddyPress Community, User Profile, Social Network & Membership Plugin for WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.2.2 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform unauthorized actions.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on integrity.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in Youzify <= 1.2.2 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Youzify the fix is 1.2.3: builds <= 1.2.2 are affected, anything from 1.2.3 onward is not.

Remediation

Update to version 1.2.3, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Youzify 1.2.3 closes this, and updating the plugin is the step that ends it.
