CVE-2025-67474 identifies a missing authorization vulnerability in the Ultimate Member ForumWP plugin, specifically affecting versions up to and including 2.1.4. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions within the forum environment. This misconfiguration can allow attackers to perform unauthorized actions such as viewing, modifying, or deleting forum content or user data without proper privileges. The issue is rooted in the plugin’s failure to enforce authorization checks on sensitive operations, effectively bypassing intended security controls. Although no public exploits have been reported to date, the vulnerability’s presence in a widely used WordPress plugin poses a significant risk. ForumWP is commonly used to manage online forums integrated into WordPress sites, which are prevalent in many European organizations for community engagement, customer support, and internal communications. The lack of a CVSS score indicates the need for an independent severity assessment. The vulnerability impacts confidentiality and integrity by potentially exposing or altering sensitive forum data. Exploitation does not require user interaction but does require the attacker to access the forum interface, which may be publicly accessible or restricted depending on configuration. The scope of affected systems includes all installations running the vulnerable versions of ForumWP. The vulnerability demands prompt attention to prevent unauthorized access and potential data compromise.

For European organizations, the missing authorization vulnerability in ForumWP could lead to unauthorized access to sensitive forum discussions, user information, and potentially administrative functions. This could result in data breaches, loss of user trust, reputational damage, and disruption of community or customer support services. Organizations relying on ForumWP for internal collaboration or external customer engagement may face risks of information leakage or malicious content injection. The impact is heightened in sectors with strict data protection regulations such as GDPR, where unauthorized data exposure can lead to significant legal and financial penalties. Additionally, compromised forums could be leveraged as a foothold for further attacks within the organization’s network. The absence of known exploits currently limits immediate risk, but the potential for exploitation remains significant if patches are not applied promptly. European organizations with large online communities or customer bases using ForumWP are particularly vulnerable to these impacts.

1. Monitor official Ultimate Member and ForumWP channels for security patches addressing CVE-2025-67474 and apply them immediately upon release. 2. Until patches are available, restrict access to forum administrative and sensitive functions using web application firewalls (WAFs) or IP whitelisting to limit exposure. 3. Review and tighten user role permissions within ForumWP to ensure minimal privileges are granted, following the principle of least privilege. 4. Conduct regular audits of forum user activities and access logs to detect any unauthorized actions or anomalies. 5. Implement multi-factor authentication (MFA) for forum administrators to reduce the risk of account compromise. 6. If feasible, isolate the forum environment from critical internal systems to limit lateral movement in case of exploitation. 7. Educate forum moderators and administrators about the vulnerability and encourage vigilance for suspicious behavior. 8. Consider temporary disabling or limiting forum functionalities that involve sensitive operations until the vulnerability is mitigated.
