  "details": "Versions of `bestzip` prior to 2.1.7 are vulnerable to Command Injection. The package fails to sanitize input rules and passes it directly to an `exec` call on the `zip` function . This may allow attackers to execute arbitrary code in the system as long as the values of `destination` is user-controlled. This only affects users with a native `zip` command available. The following examples demonstrate the issue from the CLI and also programatically:\n- `bestzip test.zip \u0027sourcefile; mkdir folder\u0027`\n- `zip({ source: \u0027sourcefile\u0027, destination: \u0027./test.zip; mkdir folder\u0027 })`",
