CVE-2025-0987
CWE-639Published: November 3, 2025· Updated: Jun 17, 2026
Official Description
Authorization Bypass Through User-Controlled Key vulnerability in CB Project Ltd. Co. CVLand allows Parameter Injection.
This issue affects CVLand: from 2.1.0 through 20251103. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Risk Analysis
This critical vulnerability in CB Project Ltd. Co. CVLand, affecting versions from 2.1.0 through 20251103, allows for an Authorization Bypass Through User-Controlled Key, leading to Parameter Injection. With a CVSS score of 9.9, this flaw could allow attackers to bypass security controls and potentially gain unauthorized access or manipulate application behavior. The absence of an EPSS score means the exploitation likelihood is not yet assessed, but the high CVSS score highlights its severity.
No public exploit is currently known for this vulnerability. However, its remote exploitability (AV:N) and low attack complexity (AC:L) make it a significant concern.
To mitigate this vulnerability, update CVLand to a patched version. Implement robust input validation and ensure proper authorization checks are in place for all user-controlled parameters.
Technical Analysis
CVE-2025-0987 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), with a CVSS base score of 9.9.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
