CVE-2025-62883 identifies a Missing Authorization vulnerability in the Premmerce User Roles WordPress plugin, specifically versions up to 1.0.13. This vulnerability arises from improperly configured access control mechanisms within the plugin, allowing users with limited privileges (requiring some level of authentication) to perform actions or access data beyond their authorization scope. The vulnerability is exploitable remotely over the network without requiring user interaction, making it a relatively straightforward attack vector once an attacker has some level of access. The CVSS v3.1 score is 4.3 (medium), reflecting limited confidentiality impact and no impact on integrity or availability. The flaw does not allow unauthenticated access but leverages privilege misconfigurations to escalate access or view restricted information. Premmerce User Roles is a plugin used to manage user roles and permissions in WordPress e-commerce sites, so exploitation could lead to unauthorized role changes or access to sensitive user data. No patches or exploits are currently publicly available, but the vulnerability is officially published and should be addressed promptly. The issue highlights the importance of strict access control validation in WordPress plugins managing user permissions.

For European organizations, especially those operating WordPress-based e-commerce platforms using the Premmerce User Roles plugin, this vulnerability could lead to unauthorized access to user role management functions. This may result in limited information disclosure or privilege escalation, potentially allowing attackers to gain elevated permissions within the site. While the direct impact on critical systems is limited, unauthorized role changes could facilitate further attacks, such as data theft or site manipulation. Organizations handling sensitive customer data or financial transactions could face compliance risks under GDPR if unauthorized access leads to data breaches. The medium severity indicates moderate risk, but the ease of exploitation by authenticated users means insider threats or compromised accounts could be leveraged. The lack of known exploits reduces immediate risk but does not eliminate the need for proactive mitigation.

1. Immediately audit and restrict user roles and permissions within WordPress to ensure least privilege principles are enforced. 2. Monitor and log all changes to user roles and permissions to detect suspicious activity early. 3. Apply patches or updates from Premmerce as soon as they become available to fix the authorization flaw. 4. Implement multi-factor authentication (MFA) for all administrative and privileged accounts to reduce risk from compromised credentials. 5. Use Web Application Firewalls (WAFs) with rules tailored to detect anomalous access patterns related to user role management. 6. Regularly review and test access control configurations in WordPress plugins, especially those managing user permissions. 7. Educate administrators and users about the risks of privilege escalation and the importance of secure credential management. 8. Consider isolating critical WordPress instances and limiting network exposure to reduce attack surface.
