CVE-2025-53773 is a command injection vulnerability classified under CWE-77, affecting Microsoft Visual Studio 2022 version 17.14. The vulnerability stems from improper neutralization of special characters in commands processed by GitHub Copilot and Visual Studio, which can be manipulated by an attacker to execute arbitrary code on the local machine. This occurs because the input handling mechanisms fail to sanitize or escape special elements that are interpreted by the command shell, leading to injection of malicious commands. The vulnerability does not require any privileges and can be triggered with user interaction, such as opening or interacting with a project or code snippet that leverages GitHub Copilot features. The impact includes full compromise of confidentiality, integrity, and availability on the affected system. The CVSS 3.1 base score is 7.8, indicating a high severity level, with an attack vector limited to local access but no privileges required. No patches or exploits are currently publicly available, but the vulnerability is officially published and recognized by Microsoft. This vulnerability highlights the risks introduced by integrating AI-assisted coding tools without robust input validation and command handling safeguards.

The vulnerability allows attackers to execute arbitrary code locally, potentially leading to full system compromise including data theft, unauthorized modifications, or system disruption. Since Visual Studio is widely used by developers, exploitation could also facilitate supply chain attacks by injecting malicious code into software projects. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk in environments where attackers can trick users into opening malicious projects or code snippets. The compromise of development environments can have cascading effects on software integrity and organizational security. Confidentiality, integrity, and availability are all at high risk, making this a critical concern for organizations relying on Visual Studio 2022 for software development.

Organizations should monitor Microsoft advisories closely and apply patches immediately once released. Until patches are available, restrict access to Visual Studio 2022 version 17.14 installations, especially limiting use of GitHub Copilot features in untrusted projects or code. Implement strict input validation and sanitization for any user-supplied data processed by development tools. Educate developers about the risks of opening untrusted code or projects and encourage use of sandboxed environments for testing. Employ endpoint protection solutions that can detect anomalous command executions. Consider disabling GitHub Copilot integration temporarily if feasible. Regularly audit development environments for suspicious activity and maintain robust backup and recovery procedures to mitigate potential damage from exploitation.
