CVE-2025-62222 is a command injection vulnerability classified under CWE-77 affecting Microsoft Visual Studio Code's 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 commands remotely over a network. The vulnerability does not require any privileges but does require user interaction, such as triggering the extension's chat feature. Exploitation can lead to full compromise of the host system, impacting confidentiality, integrity, and availability. The CVSS v3.1 score is 8.8 (high), reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and high impact on all security properties. Although no exploits are currently known in the wild, the vulnerability's nature and the widespread use of Visual Studio Code and its extensions make it a significant threat. The extension's integration with AI-driven code assistance increases the attack surface, as malicious input could be crafted to exploit the command injection flaw. The vulnerability was reserved on 2025-10-08 and published on 2025-11-11, with no patch links currently available, indicating that mitigation options are limited until an official fix is released.

For European organizations, especially those heavily reliant on Visual Studio Code for software development, this vulnerability poses a critical risk. Successful exploitation can lead to unauthorized remote code execution, allowing attackers to steal sensitive intellectual property, deploy malware, or disrupt development operations. The compromise of developer workstations can also serve as a pivot point for broader network intrusion, threatening enterprise-wide confidentiality and integrity. Given the extension's network exposure and integration with cloud services, attackers could potentially leverage this flaw to infiltrate corporate networks remotely. The impact extends beyond individual developers to entire organizations, potentially affecting software supply chains and critical infrastructure sectors reliant on secure software development practices. This risk is amplified in countries with large tech industries and extensive use of Microsoft development tools.

1. Immediately monitor official Microsoft channels for patches or updates addressing CVE-2025-62222 and apply them as soon as they become available. 2. Until a patch is released, disable or uninstall the CoPilot Chat Extension version 0.27.0 in Visual Studio Code to eliminate exposure. 3. Restrict network access to Visual Studio Code extensions by implementing firewall rules or network segmentation to limit external communication. 4. Enforce strict endpoint security policies on developer machines, including application whitelisting and behavior monitoring to detect anomalous command execution. 5. Educate developers about the risks of interacting with untrusted inputs or prompts within the CoPilot Chat Extension. 6. Employ runtime application self-protection (RASP) or endpoint detection and response (EDR) tools to identify and block suspicious activities related to command injection attempts. 7. Conduct regular security audits of development environments to ensure no unauthorized extensions or outdated versions are in use. 8. Implement multi-factor authentication and least privilege principles to reduce the impact of potential compromise.
