CVE-2025-62883 identifies a Missing Authorization vulnerability in the Premmerce User Roles WordPress plugin, specifically in versions up to 1.0.13. The vulnerability arises from incorrectly configured access control security levels within the plugin, which manages user roles and permissions for WordPress sites, commonly used in e-commerce contexts. Missing authorization means that certain functions or endpoints do not properly verify whether the requesting user has the necessary permissions to perform actions, allowing attackers to bypass intended restrictions. This can lead to unauthorized privilege escalation, where an attacker with limited access could manipulate user roles, elevate privileges, or perform administrative tasks without proper authorization. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. Although no public exploits have been reported yet, the nature of the flaw suggests that exploitation could be straightforward for attackers familiar with WordPress plugin structures. The plugin’s role in managing user permissions makes this vulnerability particularly sensitive, as it directly impacts the integrity and confidentiality of user access controls. No official patches or updates are currently linked, indicating that affected organizations should monitor vendor advisories closely. The lack of a CVSS score necessitates an independent severity assessment based on the vulnerability’s characteristics and potential impact.

For European organizations, especially those operating WordPress-based e-commerce platforms using the Premmerce User Roles plugin, this vulnerability poses a significant risk. Unauthorized access to user role management can lead to privilege escalation, allowing attackers to gain administrative control, modify or delete critical data, and disrupt business operations. This can result in data breaches, loss of customer trust, regulatory non-compliance (notably under GDPR), and financial losses. The impact on availability is moderate but could become severe if attackers leverage elevated privileges to disable security controls or delete content. Confidentiality and integrity impacts are high due to unauthorized access and potential manipulation of user roles. The absence of known exploits provides a window for proactive mitigation, but the ease of exploitation without authentication increases urgency. European organizations with complex user role hierarchies or those handling sensitive customer data are particularly vulnerable. The threat also extends to managed service providers hosting multiple WordPress sites, amplifying potential damage.

1. Immediately audit all WordPress installations for the presence of the Premmerce User Roles plugin and identify affected versions (<= 1.0.13). 2. Restrict access to the WordPress admin dashboard and plugin management interfaces to trusted IP addresses or VPNs to reduce exposure. 3. Implement strict user role and permission reviews to detect any unauthorized changes or privilege escalations. 4. Monitor logs for unusual activity related to user role modifications or access control changes. 5. Apply the vendor’s patch or update as soon as it becomes available; if no patch is yet released, consider temporarily disabling the plugin or replacing it with alternative solutions. 6. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting user role management endpoints. 7. Educate administrators on the risks of unauthorized access and enforce strong authentication mechanisms such as multi-factor authentication (MFA). 8. Regularly back up WordPress sites and databases to enable rapid recovery in case of compromise. 9. Engage in threat intelligence sharing within industry groups to stay informed about emerging exploits or mitigation strategies.
