CVE-2025-0987 is an authorization bypass vulnerability classified under CWE-639 (Authorization Bypass Through User-Controlled Key) affecting the CVLand product by CB Project Ltd. Co., specifically versions from 2.1.0 through the build dated 20251103. The vulnerability arises because CVLand improperly validates or controls keys that users can manipulate, allowing attackers with low privileges (PR:L) to inject parameters that bypass authorization mechanisms. This flaw does not require user interaction (UI:N) and can be exploited remotely (AV:N) over the network, making it highly accessible to attackers. The vulnerability impacts confidentiality and integrity severely (C:H/I:H) and has a limited effect on availability (A:L). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially authorized scope, potentially allowing attackers to access or modify data belonging to other users or system components. Although no public exploits have been reported yet, the critical CVSS score of 9.9 reflects the ease of exploitation combined with the severe impact on sensitive data and system integrity. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls. This vulnerability is particularly dangerous in environments where CVLand manages sensitive or critical data, as attackers could escalate privileges or access unauthorized information by manipulating user-controlled keys. The root cause is insufficient validation and authorization checks on user-supplied keys or parameters, which should be addressed by the vendor through secure coding practices and robust access control enforcement.

For European organizations, the impact of CVE-2025-0987 could be substantial, especially for those relying on CVLand for critical business functions or sensitive data management. Successful exploitation can lead to unauthorized access to confidential information, data tampering, and potential disruption of business processes. The integrity of data is at high risk, which could undermine trust and compliance with data protection regulations such as GDPR. Organizations in sectors like finance, healthcare, government, and critical infrastructure that use CVLand may face operational risks and reputational damage. The vulnerability’s ease of exploitation and network accessibility increase the likelihood of targeted attacks or opportunistic exploitation by cybercriminals. Additionally, the cross-scope impact means attackers could pivot within the system, escalating the severity of breaches. The absence of known exploits currently provides a window for proactive defense, but the critical severity demands immediate attention to prevent potential incidents.

1. Monitor CB Project Ltd. Co. communications closely for official patches or updates addressing CVE-2025-0987 and apply them immediately upon release. 2. Until patches are available, implement strict input validation and sanitization on all user-controlled keys or parameters within CVLand to prevent injection attacks. 3. Enforce the principle of least privilege rigorously, ensuring users have only the minimum necessary access rights to reduce the impact of potential authorization bypass. 4. Employ network segmentation and access controls to limit exposure of CVLand instances to trusted networks and users only. 5. Conduct thorough code reviews and penetration testing focused on authorization logic and parameter handling in CVLand deployments. 6. Deploy real-time monitoring and alerting for unusual access patterns or privilege escalations within CVLand environments. 7. Prepare incident response plans specific to authorization bypass scenarios to enable rapid containment and remediation. 8. Educate administrators and users about the risks of parameter injection and the importance of secure configuration. 9. Consider temporary compensating controls such as multi-factor authentication and additional logging to detect and deter unauthorized access attempts.
