Command Injection Vulnerability in GitHub Copilot and Visual Studio

CVE-2025-53773

What is CVE-2025-53773?

CVE-2025-53773 is a command injection vulnerability found in Microsoft’s GitHub Copilot and Visual Studio products. These tools are integral to many development workflows, providing code suggestions and facilitating programming tasks. The vulnerability arises from improper handling of special elements in commands, allowing unauthorized attackers to execute arbitrary code on the local environment of users. The implications of this flaw are particularly severe within environments where sensitive data or critical applications are developed, as it can lead to unauthorized code execution, compromises in application integrity, and possible damage to organizational resources.

Potential impact of CVE-2025-53773

1. Unauthorized Code Execution: Attackers can exploit this vulnerability to run arbitrary commands on the affected systems. This could lead directly to the execution of malicious payloads, providing attackers with control over systems that rely on these development tools.

2. Compromise of Development Environments: Since GitHub Copilot and Visual Studio are frequently used in coding and application development, a successful exploit could undermine the security of applications built within these environments, potentially leading to widespread vulnerabilities in production systems.

3. Data Breaches: Exploiting this vulnerability could result in sensitive data being exposed or manipulated. This risk is particularly concerning for organizations that handle confidential customer information or proprietary code, leading to financial loss and reputational damage.
