The vulnerability identified as CVE-2025-14081 affects the Ultimate Member plugin for WordPress, a widely used tool for managing user profiles, registrations, logins, member directories, content restrictions, and memberships. The flaw arises from an incorrect authorization implementation (CWE-863) in the plugin's handling of profile privacy settings. Specifically, the plugin stores field keys in an allowed fields list before performing the required permission checks (`required_perm`) during the rendering process. This sequence allows authenticated users with Subscriber-level privileges to manipulate the privacy settings of their profiles by directly modifying request parameters, such as setting their profile visibility to "Only me," even when administrators have explicitly disabled this option for their role. The vulnerability affects all versions up to and including 2.11.0. The CVSS 3.1 base score is 4.3 (medium severity), reflecting that the attack vector is network-based, requires low attack complexity, and privileges at the level of a subscriber, with no user interaction needed. The impact is limited to integrity, as attackers can alter privacy settings but cannot access or disclose other users' data. No known exploits have been reported in the wild, and no patches have been published yet. The flaw could be leveraged to circumvent organizational privacy policies or disrupt user trust by altering profile visibility settings.

For European organizations, this vulnerability could undermine user privacy controls on websites using the Ultimate Member plugin, potentially leading to unauthorized changes in profile visibility. While it does not directly expose confidential data, the ability for low-privileged users to alter privacy settings can result in inconsistent enforcement of privacy policies, damaging user trust and possibly violating GDPR requirements related to data protection and user consent. Organizations relying on this plugin for membership or community management may face reputational risks and compliance challenges if user profiles are improperly exposed or restricted. The impact is more pronounced for websites with sensitive user communities or where strict privacy settings are mandated. Since exploitation requires authenticated access, the threat is limited to registered users, but given the commonality of subscriber roles in WordPress sites, the attack surface is broad. The absence of known exploits reduces immediate risk, but the vulnerability should be addressed proactively to prevent misuse.

European organizations should immediately audit their WordPress sites using the Ultimate Member plugin to identify affected versions (up to 2.11.0). Until an official patch is released, administrators can implement the following mitigations: 1) Restrict Subscriber-level user capabilities further by customizing roles to limit profile editing permissions; 2) Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious parameter manipulation attempts targeting profile privacy settings; 3) Monitor logs for unusual changes in profile privacy configurations; 4) Consider temporarily disabling the Ultimate Member plugin or limiting its use to trusted users only; 5) Keep WordPress core and all plugins updated and subscribe to vendor advisories for timely patch releases; 6) Educate site administrators and users about the risk and encourage reporting of unexpected profile behavior. These steps go beyond generic advice by focusing on role capability management and proactive monitoring specific to this vulnerability's exploitation vector.
