CVE-2025-62222 is a command injection vulnerability classified under CWE-77 affecting Microsoft Visual Studio Code CoPilot Chat Extension version 0.27.0. The flaw arises from improper neutralization of special elements used in commands, allowing an attacker to inject and execute arbitrary code remotely over a network. This vulnerability does not require any privileges but does require user interaction, such as triggering the extension's chat feature with crafted input. The attack vector is network-based, and exploitation can lead to full compromise of the host system running the vulnerable extension. The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution can lead to data theft, system manipulation, or denial of service. Although no public exploits are currently known, the high CVSS score of 8.8 indicates a serious risk. The extension is widely used by developers leveraging AI-assisted coding within Visual Studio Code, making it a valuable target. The vulnerability was reserved on 2025-10-08 and published on 2025-11-11, with no patch links currently available, suggesting a patch is pending or in progress. Organizations relying on this extension should consider immediate mitigation steps to prevent exploitation.

For European organizations, this vulnerability poses a significant risk, particularly for software development firms, IT departments, and enterprises heavily reliant on Visual Studio Code and its CoPilot Chat Extension. Successful exploitation could lead to unauthorized remote code execution, enabling attackers to steal sensitive intellectual property, deploy malware, or disrupt development workflows. The compromise of developer machines can also serve as a pivot point for broader network intrusion, potentially affecting critical infrastructure and business operations. Given the widespread adoption of Microsoft products and Visual Studio Code in Europe, the impact could be extensive, affecting confidentiality of proprietary code, integrity of software builds, and availability of development environments. The requirement for user interaction somewhat limits automated exploitation but does not eliminate risk, especially in environments where developers frequently interact with the extension. The absence of known exploits in the wild currently reduces immediate risk but should not lead to complacency.

1. Immediately disable or uninstall the vulnerable CoPilot Chat Extension version 0.27.0 until a patch is released. 2. Monitor official Microsoft channels for patch announcements and apply updates promptly once available. 3. Implement strict input validation and sanitization on any user inputs interacting with the extension or related services to prevent injection. 4. Restrict network access to development machines running Visual Studio Code to trusted networks and users only. 5. Employ endpoint detection and response (EDR) solutions to monitor for unusual process executions or network activity originating from developer workstations. 6. Educate developers about the risks of interacting with untrusted inputs or commands within the extension. 7. Use application whitelisting to prevent unauthorized code execution on developer machines. 8. Conduct regular security audits of development environments to identify and remediate potential vulnerabilities.
