Overview
Affected versions of this package are vulnerable to Unsafe Dependency Resolution when the gh codespace jupyter process opens a JupyterLab URL supplied by a process inside a Codespace without validating that it is a loopback HTTP or HTTPS address. An attacker can execute arbitrary commands on the user's system by providing a crafted vscode:// or vscode-insiders:// URL, which is then handed to VS Code.
