Executive Summary

This vulnerability in Visual Studio Code is caused by an incomplete list of disallowed inputs, which allows an unauthorized attacker to bypass a security feature locally. This means the security mechanism designed to block certain inputs fails to do so, potentially letting malicious inputs through.

Impact Analysis

An attacker could exploit this to bypass security features on your system, potentially leading to unauthorized access or execution of malicious code. Since the attack is local, it requires the attacker to have some access to your system already.

Mitigation Strategies

Apply the latest security update from Microsoft for Visual Studio Code to address the incomplete list of disallowed inputs. Monitor the Microsoft Security Response Center for updates and patches.
