CVE-2025-53773 is a command-injection vulnerability affecting GitHub Copilot and Visual Studio 2022. Malicious instructions embedded in repository content, such as a malicious rules file or project file, can be processed by the coding agent and cause execution of an embedded command. The flaw enables an unauthorized attacker to execute code locally in the developer environment.

A high-severity local command-injection vulnerability affecting GitHub Copilot in Visual Studio 2022. Opening a malicious project or file can cause the coding agent to process embedded content and execute a command, potentially fully compromising confidentiality, integrity, and availability.
A command injection vulnerability affecting GitHub Copilot / Visual Studio workflow, where a malicious rules file in a repository can cause local arbitrary code execution when a developer opens the project and Copilot processes it.
A cited high-severity vulnerability associated with indirect prompt injection in AI agents, where the agent trusted untrusted content.
A separate previously patched GitHub Copilot vulnerability that allowed prompt injection to enable YOLO mode by modifying workspace settings.
