Critical (9.8) in microsoft workspace-tools. EPSS 6.7% chance of exploitation in the next 30 days. Fixed in workspace-tools 0.18.4.
The package workspace-tools before 0.18.4 are vulnerable to Command Injection via git argument injection. When calling the fetchRemoteBranch(remote: string, remoteBranch: string, cwd: string) function, both the remote and remoteBranch parameters are passed to the git fetch subcommand in a way that additional flags can be set. The additional flags can be used to perform a command injection.
