Executive brief
Visual Studio Code is a widely-used code editor that developers rely on for their daily work. A vulnerability in how the application compares security-related values could allow an attacker on the network to bypass important security protections, potentially gaining unauthorized access to code or sensitive information open in the editor.
Technical details
The vulnerability stems from an incomplete comparison with missing factors in Visual Studio Code's security validation logic. This logic flaw allows an attacker to bypass a security feature via a network-based attack vector without requiring user interaction or prior authentication. An attacker can exploit this to circumvent protections that would normally restrict unauthorized access. A patch from Microsoft is available through their Security Update Guide.
