Description

Authorization bypass through user-controlled key in Visual Studio Code allows an unauthorized attacker to bypass a security feature over a network.

FAQ

How could an attacker exploit this vulnerability? An attacker could convince a user to open a specially crafted Visual Studio Code workspace. The workspace could cause Visual Studio Code to connect to an attacker-controlled service and bypass Workspace Trust restrictions. Successful exploitation could allow the attacker to access local data or execute code in the context of the user. User interaction is required, but the user does not need to trust the workspace. What security feature could be bypassed by successfully exploiting this vulnerability? An attacker who successfully exploited this vulnerability could bypass the Visual Studio Code Workspace Trust feature, allowing content from an untrusted workspace to run commands or code without the user first granting trust. See Workspace Trust for more information.
