CVE-2025-60098 is a security vulnerability classified under CWE-862, which pertains to missing authorization controls. This vulnerability affects the WordPress plugin 'Theme My Login' developed by Jeff Farthing, specifically versions up to 7.1.12. The flaw arises from incorrectly configured access control security levels, allowing unauthorized users to perform actions that should be restricted. The vulnerability does not require any authentication or user interaction to exploit, and it can be triggered remotely over the network (AV:N). The CVSS v3.1 base score is 6.5, indicating a medium severity level. The impact vector shows that while confidentiality is not affected, the integrity and availability of the affected system can be compromised. An attacker exploiting this vulnerability could alter or disrupt the normal functioning of the login theme, potentially leading to defacement, denial of service, or unauthorized changes to login-related configurations. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that mitigation may require manual configuration adjustments or awaiting an official update. The vulnerability's presence in a widely used WordPress plugin makes it a significant concern for websites relying on Theme My Login for user authentication and login customization.

For European organizations, the impact of CVE-2025-60098 can be substantial, especially for those relying on WordPress sites with the Theme My Login plugin for customer portals, intranets, or e-commerce platforms. The missing authorization controls could allow attackers to manipulate login processes or disrupt user access, potentially leading to service outages or unauthorized modifications. This can damage organizational reputation, cause loss of user trust, and result in regulatory non-compliance under GDPR if personal data integrity or availability is affected. Additionally, compromised login themes could be leveraged as a foothold for further attacks, including privilege escalation or lateral movement within the network. Organizations in sectors such as finance, healthcare, and government, which often use WordPress for public-facing or internal applications, may face heightened risks. The medium severity rating suggests that while the vulnerability is not critical, it still poses a meaningful threat that should be addressed promptly to prevent exploitation.

To mitigate CVE-2025-60098, European organizations should take the following specific actions: 1) Immediately audit all WordPress installations to identify the presence and version of the Theme My Login plugin. 2) Restrict access to the WordPress admin and login-related endpoints using web application firewalls (WAFs) or IP whitelisting to limit exposure. 3) Implement strict role-based access controls within WordPress to minimize the permissions granted to users and plugins. 4) Monitor logs for unusual access patterns or unauthorized changes related to login themes. 5) If no official patch is available, consider temporarily disabling or replacing the Theme My Login plugin with alternative, well-maintained login management plugins that have robust authorization controls. 6) Stay informed through vendor advisories and security mailing lists for the release of patches or updates addressing this vulnerability. 7) Conduct penetration testing focused on access control mechanisms around login and authentication components to detect similar weaknesses. These steps go beyond generic advice by focusing on proactive detection, access restriction, and contingency planning specific to the affected plugin and its role in authentication workflows.
