How to fix?

Upgrade @hoppscotch/cli to version 0.8.0 or higher.

Overview

@hoppscotch/cli is an A CLI to run Hoppscotch test scripts in CI environments.

Affected versions of this package are vulnerable to Arbitrary Command Injection due to the improper handling of user-supplied input in the vm module context. An attacker can execute arbitrary system commands on the victim's machine by crafting a malicious pre-request script that escapes the sandbox environment.

Note

This is only exploitable if the victim downloads and runs a malicious Hoppscotch collection with the CLI tool.

Workaround

This vulnerability can be mitigated by using alternative safe JavaScript sandboxing libraries or by introducing an --enable-scripting flag for the CLI and disabling scripting by default.
