At a glance

CVE-2024-0687 is a medium-severity Improper Access Control vulnerability in the Restrict User Access WordPress plugin, affecting versions <= 2.5.

The issue is fixed in version 2.6; sites on affected versions should update now. Disclosed February 2024, reported by Francesco Carlucci.

Vulnerability Overview

The Restrict User Access – Ultimate Membership & Content Protection plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 2.5 via API. This makes it possible for unauthenticated attackers to obtain the contents of posts and pages via API.

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 privileges on the target site, and no interaction from a victim user.

CWE-284: Improper Access Control

Reaching this weakness in Restrict User Access <= 2.5 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Restrict User Access the fix is 2.6: builds <= 2.5 are affected, anything from 2.6 onward is not.

Remediation

Update to version 2.6, 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: Restrict User Access 2.6 closes this, and updating the plugin is the step that ends it.
