Advisory Weakness Curation

Command Injection in bestzip 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: - `bestzip test.zip 'sourcefile; mkdir folder'` - `zip({ source: 'sourcefile', destination: './test.zip; mkdir folder' })`
