CVE-2025-67474 identifies a missing authorization vulnerability in the Ultimate Member ForumWP plugin, specifically affecting versions up to and including 2.1.4. This vulnerability arises from improperly configured access control mechanisms within the plugin, which allow authenticated users with limited privileges to perform unauthorized actions. The flaw does not require user interaction and can be exploited remotely over the network, increasing its risk profile. The vulnerability impacts the integrity of the forum data by enabling unauthorized modifications or actions that should be restricted. However, it does not affect confidentiality or availability directly. The CVSS score of 4.3 (medium) reflects the limited scope and impact, requiring at least some level of privileges (PR:L) but no user interaction (UI:N). No public exploits have been reported yet, indicating that exploitation in the wild is not currently observed. ForumWP is a WordPress plugin used to add forum capabilities to websites, often deployed by organizations to facilitate community engagement. The missing authorization issue could allow malicious insiders or compromised accounts to escalate privileges or manipulate forum content, potentially undermining trust and user experience. The vulnerability was published on December 9, 2025, and no patches or fixes are currently linked, suggesting that users should monitor vendor communications closely. The root cause is an incorrect implementation of access control checks, a common security weakness that can be mitigated by rigorous permission validation and role enforcement.

For European organizations, the primary impact of CVE-2025-67474 lies in the potential unauthorized modification of forum content or escalation of privileges within community platforms using ForumWP. This can lead to reputational damage, loss of user trust, and potential misinformation dissemination if malicious actors manipulate forum discussions. While the vulnerability does not compromise sensitive data confidentiality or system availability, integrity violations can disrupt normal operations and community management. Organizations relying on ForumWP for customer support, internal collaboration, or public engagement may face operational disruptions or increased administrative overhead to detect and remediate unauthorized changes. The requirement for some level of authentication limits exposure to external anonymous attackers but does not eliminate risk from compromised or insider accounts. Given the widespread use of WordPress and its plugins in Europe, especially in sectors like education, government, and SMEs, the vulnerability could affect a significant number of installations if not addressed promptly.

1. Monitor the Ultimate Member vendor channels for official patches or updates addressing CVE-2025-67474 and apply them immediately upon release. 2. In the absence of patches, conduct a thorough review of ForumWP access control configurations, ensuring that permission checks are correctly enforced for all user roles and actions. 3. Implement strict user role management policies, minimizing privileges granted to forum users and administrators to the least necessary. 4. Enable detailed logging and monitoring of forum activities to detect unusual or unauthorized actions promptly. 5. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting ForumWP endpoints. 6. Educate forum administrators and moderators on recognizing signs of unauthorized content changes or privilege misuse. 7. If feasible, isolate critical forum installations in segmented network zones to limit lateral movement in case of compromise. 8. Regularly audit user accounts and revoke access for inactive or suspicious users. 9. Evaluate alternative forum solutions with stronger security postures if timely patching is not possible. 10. Incorporate this vulnerability into incident response plans to ensure rapid containment if exploitation is detected.
