GitHub Copilot for JetBrains Command Injection RCE
CVE-2025-64671 is a command injection vulnerability in the GitHub Copilot plugin for JetBrains IDEs. The issue is described as improper neutralization of special elements used in a command, allowing an unauthorized attacker to execute code locally. Available reporting indicates the flaw can be triggered through malicious cross-prompt injection delivered via untrusted files or Model Context Protocol (MCP) servers. In affected configurations, attacker-controlled prompt content can cause Copilot to append unintended commands to otherwise permitted terminal actions, including bypassing or piggybacking on the plugin's terminal auto-approve behavior. Although Microsoft classifies the resulting execution as local, multiple sources note that a remote attacker could plausibly trigger exploitation through social engineering by inducing a developer to open malicious content or interact with a malicious MCP source.
