Executive brief
Simple Membership is a WordPress plugin used to manage member-only content and subscriptions. A security flaw allows unauthenticated visitors to bypass access controls and perform actions that should be restricted to authorized users. This could allow an attacker to modify site settings or member data without permission, potentially disrupting operations.
Technical details
The Simple Membership plugin for WordPress (versions 4.7.1 and below) contains a broken access control vulnerability due to missing authorization checks (CWE-862). An unauthenticated remote attacker can exploit this flaw by sending crafted network requests to trigger functions that lack proper permission validation. Successful exploitation allows the attacker to execute higher-privileged actions, potentially leading to unauthorized data modification or integrity loss. The issue is resolved in version 4.7.2.
