CVE-2025-64630 is a missing authorization vulnerability identified in the Strategy11 Team Business Directory plugin, affecting versions up to and including 6.4.19. The flaw stems from improperly configured access control mechanisms that fail to enforce authorization checks correctly, allowing users with elevated privileges to perform actions beyond their intended scope. The vulnerability is network exploitable (AV:N) and requires high privileges (PR:H) but no user interaction (UI:N). The impact includes limited confidentiality, integrity, and availability loss, as indicated by the CVSS vector (C:L/I:L/A:L). Although no known exploits are currently active in the wild, the vulnerability poses a risk to environments where the plugin is deployed, particularly if privilege escalation or lateral movement is possible. The absence of patches at the time of reporting necessitates proactive mitigation. The vulnerability highlights the importance of robust access control validation within web application plugins managing business directory data.

For European organizations, the vulnerability could lead to unauthorized access or modification of business directory information, potentially exposing sensitive organizational data or disrupting directory services. While the impact is rated medium, organizations relying on this plugin for internal or public-facing directories may experience data integrity issues or service availability degradation. Given the network accessibility of the vulnerability, attackers with elevated privileges could exploit it remotely, increasing risk in multi-tenant or cloud-hosted environments. The exposure could also facilitate further attacks if combined with privilege escalation vulnerabilities. Confidentiality impacts, although limited, could affect business partner or client information stored in the directory, raising compliance concerns under GDPR. Availability impacts, while limited, could disrupt business operations relying on directory services.

European organizations should immediately audit and tighten access control configurations within the Business Directory plugin to ensure only authorized users have elevated privileges. Implement the principle of least privilege rigorously, restricting high privilege roles to trusted administrators. Monitor logs for unusual access patterns or unauthorized attempts to modify directory data. Since no patches are currently available, consider temporarily disabling the plugin or restricting its network accessibility to trusted internal networks. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. Stay informed on vendor updates and apply security patches promptly once released. Additionally, conduct regular security assessments of plugins and third-party components to identify and remediate similar authorization issues proactively.
