bestzip versions 2.2.6 and 3.0.2 contain an argument injection vulnerability in the nativeZip function that allows attackers to inject arbitrary arguments to the Info-ZIP backend. Attackers can supply a malicious destination path combined with crafted source entries to execute arbitrary commands with Node.js process privileges. Fixed in 2.2.7 and 3.0.3.
