At a glance

CVE-2024-5596 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the ARMember Premium WordPress plugin, affecting versions <= 6.7. It carries a CVSS score of 6.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 6.7.1; sites on affected versions should update now. Disclosed June 2024, reported by István Márton.

Vulnerability Overview

The ARMember Premium plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 6.7. This is due to incorrectly implemented nonce validation function on multiple functions. This makes it possible for unauthenticated attackers to modify, or delete user meta and plugin options which can lead to limited privilege escalation.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in ARMember Premium <= 6.7 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For ARMember Premium the fix is 6.7.1: builds <= 6.7 are affected, anything from 6.7.1 onward is not.

Remediation

Update to version 6.7.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to ARMember Premium: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: ARMember Premium 6.7.1 closes this, and updating the plugin is the step that ends it.
