CVE-2025-0987 is an authorization bypass vulnerability classified under CWE-639 in the CVLand product by CB Project Ltd. Co. The flaw arises from improper handling of user-controlled keys, enabling parameter injection that bypasses authorization mechanisms. This allows an attacker with low privileges to escalate access, potentially compromising confidentiality and integrity of the system. The vulnerability affects versions from 2.1.0 through 20251103. The vendor was contacted but did not respond, and no patch or official remediation has been published.

Successful exploitation can lead to complete compromise of confidentiality and integrity of the affected system, as unauthorized access is gained through bypassing authorization controls. Availability impact is low. Given the critical CVSS score of 9.9, the vulnerability poses a severe risk to affected deployments.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded and no patch or workaround is currently available, organizations should consider restricting access to affected versions and monitor for suspicious activity related to authorization bypass attempts. Avoid deploying or upgrade from affected versions if possible until an official fix is released.
