Summary
Azure CLI contained a code injection vulnerability that could be exploited in
a scenario where the host runs a command where parameter values have been provided
by an external untrusted source - these could be specially crafted in such a way
as to exploit the vulnerability, leading to remote code execution on the host.
The vulnerability is only applicable when the Azure CLI command is run on a Windows
machine and with any version of PowerShell and when the parameter value contains
the `&` or `|` symbols.
