CVE-2025-11491 is a security vulnerability identified in the wonderwhy-er DesktopCommanderMCP software, specifically affecting all versions up to 0.2.13. The vulnerability resides in the CommandManager function within the source file src/command-manager.ts, where improper input handling leads to OS command injection. This means an attacker can remotely craft malicious inputs that are passed to the operating system shell, allowing arbitrary command execution on the affected host. The vulnerability does not require user interaction but does require the attacker to have low-level privileges on the system, which could be obtained through other means or misconfigurations. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vulnerability has been publicly disclosed with exploit details available, increasing the risk of exploitation. However, no confirmed active exploitation in the wild has been reported yet. The lack of patches at the time of disclosure means organizations must rely on interim mitigations. The vulnerability could be leveraged to execute arbitrary commands, potentially leading to data theft, system compromise, lateral movement, or denial of service depending on the commands executed. The affected software is used in desktop management contexts, which may be integrated into enterprise environments, increasing the potential impact if exploited.

For European organizations, exploitation of CVE-2025-11491 could lead to unauthorized remote command execution on systems running DesktopCommanderMCP, risking confidentiality, integrity, and availability of critical systems. Attackers could execute arbitrary commands to exfiltrate sensitive data, disrupt services, or pivot within networks. Given the software’s role in desktop management, compromise could facilitate widespread control over endpoint devices, impacting operational continuity. The medium CVSS score reflects moderate risk, but the public availability of exploit details increases urgency. Organizations in sectors with high reliance on desktop management tools—such as finance, manufacturing, and government—face elevated risks. Additionally, the vulnerability could be exploited as a foothold in targeted attacks against European enterprises, especially where network segmentation or access controls are weak. The absence of known exploits in the wild currently limits immediate impact but does not preclude future attacks. Without timely mitigation, the threat could escalate, particularly in environments with exposed or poorly secured DesktopCommanderMCP instances.

1. Monitor wonderwhy-er official channels for patches addressing CVE-2025-11491 and apply updates promptly once available. 2. Until patches are released, restrict network access to DesktopCommanderMCP services using firewalls or network segmentation to limit exposure to trusted hosts only. 3. Implement strict input validation and sanitization on any interfaces interacting with the CommandManager function to prevent injection of malicious commands. 4. Employ application whitelisting and restrict execution privileges on systems running DesktopCommanderMCP to limit the impact of potential command injection. 5. Conduct regular security audits and vulnerability scans to identify and remediate instances of vulnerable DesktopCommanderMCP versions. 6. Enhance monitoring and logging for unusual command execution patterns or suspicious activities on affected hosts to enable early detection. 7. Educate system administrators about the risks and signs of exploitation related to this vulnerability to improve incident response readiness. 8. Consider deploying host-based intrusion prevention systems (HIPS) that can detect and block command injection attempts targeting the affected software.
