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. The vulnerability does not require any privileges (PR:N) but does require user interaction (UI:R), such as engaging with the chat extension interface. The CVSS v3.1 score of 8.8 reflects a high severity due to the potential for complete compromise of confidentiality, integrity, and availability of affected systems. The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component and its host environment. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation make it a critical risk for developers and organizations relying on this extension. The extension is widely used in software development environments, making it a valuable target for attackers aiming to execute arbitrary commands remotely, potentially leading to system takeover, data exfiltration, or disruption of development workflows.

For European organizations, this vulnerability poses a significant threat to the security of development environments. Exploitation could lead to unauthorized code execution, enabling attackers to compromise source code integrity, steal sensitive intellectual property, or deploy malware within corporate networks. The impact extends to potential disruption of software development pipelines, causing operational delays and financial losses. Given the widespread use of Visual Studio Code and its extensions across Europe, especially in countries with robust IT sectors, the risk of targeted attacks is substantial. Confidentiality breaches could expose proprietary data, while integrity violations might introduce backdoors or malicious code into software products. Availability could also be affected if attackers disrupt development tools or infrastructure. The lack of required privileges lowers the barrier for exploitation, increasing the likelihood of successful attacks in environments where the vulnerable extension is present.

1. Immediately update the Visual Studio Code CoPilot Chat Extension to a patched version once available from Microsoft. 2. Until a patch is released, disable or uninstall the vulnerable extension (version 0.27.0) to prevent exploitation. 3. Implement strict input validation and sanitization on any user inputs processed by the extension or related tooling to prevent injection of malicious commands. 4. Monitor network traffic and logs for unusual command execution patterns or unauthorized access attempts related to the extension. 5. Educate developers and users about the risks of interacting with untrusted inputs within the extension interface. 6. Employ application whitelisting and endpoint protection solutions to detect and block unauthorized code execution. 7. Regularly audit and review installed extensions and their versions to ensure compliance with security policies. 8. Coordinate with IT and security teams to integrate vulnerability scanning for development tools into the organizational security posture.
