CyberRota Analysis
AI-GeneratedThe Ultimate Member plugin for WordPress is vulnerable to an authorization bypass that allows unauthenticated attackers to access privacy-restricted member profile information through the publicly accessible wp_ajax_nopriv_um_get_members endpoint. This flaw stems from inadequate verification of user permissions and the exposure of a nonce that does not enforce meaningful access control. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of unauthorized data exposure.

Original NVD Description
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.13.1 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to view privacy-restricted member profile field values — including fields explicitly configured as owner-only, members-only, or role-restricted — by querying the publicly accessible wp_ajax_nopriv_um_get_members endpoint. The nonce required by the endpoint ('um-frontend-nonce') is emitted to all unauthenticated visitors via wp_localize_script, meaning it provides no meaningful access control and any anonymous visitor can satisfy the endpoint's authentication requirements.
