CVE-2024-35700 identifies an Incorrect Privilege Assignment vulnerability in the DeluxeThemes Userpro plugin, specifically affecting versions up to and including 5.1.8. Userpro is a widely used WordPress plugin that manages user profiles and membership functionalities. The vulnerability arises from improper assignment or enforcement of user privileges, allowing attackers to escalate their permissions beyond intended limits. This could enable unauthorized users to perform administrative or restricted actions, such as modifying user data, changing configurations, or accessing sensitive information. The vulnerability was reserved in May 2024 and published in June 2024, with no CVSS score assigned yet and no known active exploits reported. The lack of a patch link suggests that a fix may still be pending or in development. Incorrect privilege assignment vulnerabilities are critical because they undermine the fundamental access control mechanisms, potentially leading to full compromise of the affected system. Since Userpro is integrated into many WordPress sites globally, exploitation could affect a wide range of organizations, especially those relying on Userpro for membership management and user authentication. Attackers typically exploit such vulnerabilities by leveraging flaws in role management or capability checks, often requiring only authenticated access but no additional user interaction. The technical details indicate the vulnerability was identified and assigned by Patchstack, a known security entity specializing in WordPress plugin vulnerabilities.

The impact of CVE-2024-35700 can be significant for organizations using the Userpro plugin. Successful exploitation allows attackers to escalate privileges, potentially gaining administrative control over the affected WordPress site. This can lead to unauthorized data access, modification or deletion of user profiles, installation of malicious code, and disruption of normal site operations. Confidential user information, including personal data and membership details, could be exposed or altered, violating privacy and compliance requirements. Integrity of the website content and configurations may be compromised, enabling attackers to maintain persistent access or pivot to other internal systems. Availability could also be affected if attackers disrupt user access or site functionality. The broad use of WordPress and Userpro in various sectors, including e-commerce, education, and community platforms, increases the potential scope of impact. Organizations without timely mitigation may face reputational damage, legal consequences, and financial losses due to data breaches or service interruptions.

To mitigate CVE-2024-35700, organizations should immediately audit user roles and permissions within the Userpro plugin to identify and restrict any excessive privileges. Until an official patch is released, consider temporarily disabling Userpro or limiting its use to trusted administrators only. Implement strict access controls on the WordPress admin dashboard and enable multi-factor authentication to reduce the risk of unauthorized access. Monitor logs for unusual privilege escalations or administrative actions that could indicate exploitation attempts. Regularly update WordPress core and all plugins to the latest versions once patches become available. Employ web application firewalls (WAFs) with rules targeting privilege escalation attempts in WordPress environments. Additionally, conduct penetration testing focused on role and permission management to detect similar vulnerabilities. Maintain backups of site data and configurations to enable quick recovery if compromise occurs. Engage with the vendor or security community for updates on patches and advisories related to this vulnerability.
