CVE-2025-62883 identifies a missing authorization vulnerability in the Premmerce User Roles plugin, a WordPress extension designed to manage user roles and permissions for e-commerce sites. The vulnerability exists because the plugin fails to enforce proper access control checks on certain functionality, allowing authenticated users with limited privileges to access or perform actions beyond their intended scope. Specifically, the flaw arises from incorrectly configured security levels that do not verify whether a user is authorized to execute specific operations, leading to potential unauthorized information disclosure. The vulnerability affects all versions up to and including 1.0.13. Exploitation requires the attacker to be authenticated with at least some privileges (PR:L) but does not require user interaction (UI:N), and can be performed remotely over the network (AV:N). The impact is primarily on confidentiality (C:L), with no direct impact on integrity or availability. While no public exploits have been reported, the vulnerability could be leveraged to gain unauthorized access to sensitive user role information or configuration data, which could facilitate further privilege escalation or targeted attacks. The absence of patches at the time of publication necessitates immediate attention to access control policies and monitoring. This vulnerability is particularly relevant for WordPress-based e-commerce sites in Europe using Premmerce User Roles, as unauthorized access to role configurations could compromise customer data privacy and compliance with regulations such as GDPR.

For European organizations, this vulnerability poses a moderate risk primarily to the confidentiality of user role and permission data within WordPress e-commerce environments. Unauthorized access to role configurations can lead to exposure of sensitive information about user privileges, potentially enabling attackers to plan further privilege escalation or targeted attacks. This is especially critical for organizations handling personal data subject to GDPR, where unauthorized disclosure could result in regulatory penalties and reputational damage. Although the vulnerability does not directly affect system integrity or availability, the indirect consequences of compromised access controls could disrupt business operations or lead to data breaches. Organizations in sectors such as retail, finance, and healthcare that rely on Premmerce User Roles for managing user permissions are at higher risk. The medium severity rating reflects the need for timely mitigation but indicates that the vulnerability is not trivially exploitable by unauthenticated attackers, somewhat limiting its immediate impact.

To mitigate CVE-2025-62883, European organizations should first verify if they are using Premmerce User Roles plugin version 1.0.13 or earlier. Immediate steps include restricting user privileges to the minimum necessary, ensuring that only trusted users have authenticated access to the WordPress admin area. Implement strict role-based access control policies and audit existing user roles for any excessive permissions. Monitor logs for unusual access patterns related to user role management functions. Since no official patch is available at the time of publication, consider temporarily disabling the plugin or restricting its functionality via custom code or security plugins that enforce additional authorization checks. Keep abreast of updates from the vendor and apply patches promptly once released. Additionally, conduct regular security assessments of WordPress installations and educate administrators about the risks of misconfigured access controls. Employ web application firewalls (WAFs) to detect and block suspicious requests targeting user role management endpoints.
