CVE-2025-62222
Published: 11 November 2025
Description
Improper neutralization of special elements used in a command ('command injection') in Visual Studio Code CoPilot Chat Extension allows an unauthorized attacker to execute code over a network.
Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the CVE by requiring timely identification, reporting, and correction of the command injection flaw through patching the Visual Studio Code CoPilot Chat Extension.
Prevents command injection exploitation by enforcing proper information input validation and sanitization at entry points in the chat extension's command processing.
Mitigates risk by restricting or approving user-installed software like the vulnerable CoPilot Chat Extension, preventing its deployment on systems.
Security SummaryAI
CVE-2025-62222 is a command injection vulnerability stemming from improper neutralization of special elements used in a command, classified under CWE-20 and CWE-77. It affects the Visual Studio Code CoPilot Chat Extension, enabling an unauthorized attacker to execute arbitrary code over a network. The vulnerability received a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact on confidentiality, integrity, and availability.
An attacker can exploit this vulnerability remotely with low complexity and no required privileges, but it necessitates user interaction, such as clicking a malicious link or engaging with crafted content in the extension's chat interface. Successful exploitation allows the attacker to execute arbitrary commands on the victim's machine, potentially leading to full system compromise, data theft, or further lateral movement within the environment.
